The %pe format specifier is designed to print error pointers. It prints
a symbolic error name (eg. -EINVAL) and it makes the code simpler by
omitting PTR_ERR().
This patch fixes this cocci report:

The dev_err_probe() doesn't do anything when error is '-ENOMEM'.
Therefore, remove the useless call to dev_err_probe(), and just
return the value instead.

The fmh_gpib driver contains a device reference count leak in
fmh_gpib_attach_impl() where driver_find_device() increases the
reference count of the device by get_device() when matching but this
reference is not properly decreased. Add put_device() in
fmh_gpib_detach(), which ensures that the reference count of the
device is correctly managed.
Found by code review.

When the ATN (Attention) line is asserted during a read we get a
NIUSB_ATN_STATE_ERROR during a read. For the controller to send a
device clear it asserts ATN. Normally this is an error but in the case
of a device clear it should be regarded as an interrupt.
Return -EINTR when the Device Clear Active State (DCAS) is entered
else signal an error with dev_dbg with status instead of just dev_err.

This driver was not sending device clear or trigger events when the
board entered the DCAS or DTAS state respectively in device mode.
DCAS is the Device Clear Active State which is entered on receiving a
selective device clear message (SDC) or universal device clear message
(DCL) from the controller in charge.
DTAS is the Device Trigger Active State which is entered on receiving
a group execute trigger (GET) message from the controller.
In order for an application, implementing a particular device, to
detect when one of these states is entered the driver needs to send
the appropriate event.
Send the appropriate gpib_event when DCAS or DTAS is set in the
reported status word. This sets the DCAS or DTAS bits in the board's
status word which can be monitored by the application.

EOI (End Or Identify) is a hardware line on the GPIB bus that can be
asserted with the last byte of a message to indicate the end of the
transfer to the receiving device.
In this driver, a write with send_eoi true is done in 3 parts:
Send first byte directly
Send remaining but 1 bytes using the fifo
Send the last byte directly with EOI asserted
The first byte in a write is always sent by writing to the tms9914
chip directly to setup for the subsequent fifo transfer. We were not
checking for a 1 byte write with send_eoi true resulting in EOI not
being asserted. Since the fifo transfer was not executed
(fifotransfersize == 0) the retval in the test after the fifo transfer
code was still 1 from the preceding direct write. This caused it to
return without executing the final direct write which would have sent
an unsollicited extra byte.
For a 2 byte message the first byte was sent directly. But since the
fifo transfer was not executed (fifotransfersize == 1) and the retval
in the test after the fifo transfer code was still 1 from the
preceding first byte write it returned before the final direct byte
write with send_eoi true. The second byte was then sent as a separate
1 byte write to complete the 2 byte write count again without EOI
being asserted as above.
Only send the first byte directly if more than 1 byte is to be
transferred with send_eoi true.
Also check for retval < 0 for the error return in case the fifo code
is not used (1 or 2 byte message with send_eoi true).

The irq handler iterates through the interrupt bits one by one in a while()
loop, clearing one bit at a time. This is unnecessary and inefficient, as
the 'Interrupt Status Register' can be cleared with a single write
operation.
Also the irq handler checks for some interrupts that are masked out in the
'Interrupt Enable Register', so they are never triggered.
Simplify the irq handler by removing the checks for interrupts that are
masked out and clear the whole 'Interrupt Status Register' in one go. The
macros that are no longer relevant are also removed.

Pull Char/Misc/IIO/Binder updates from Greg KH:
"Here is the big set of char/misc/iio and other driver subsystem
changes for 6.18-rc1.
Loads of different stuff in here, it was a busy development cycle in
lots of different subsystems, with over 27k new lines added to the
tree.
Included in here are:
- IIO updates including new drivers, reworking of existing apis, and
other goodness in the sensor subsystems
- MEI driver updates and additions
- NVMEM driver updates

- coresight driver updates and additions
- MHI driver updates
- comedi driver updates and fixes
- extcon driver updates
- interconnect driver additions
- eeprom driver updates and fixes
- minor UIO driver updates
- tiny W1 driver updates
But the majority of new code is in the rust bindings and additions,
which includes:
- misc driver rust binding updates for read/write support, we can now
write "normal" misc drivers in rust fully, and the sample driver
shows how this can be done.
- Initial framework for USB driver rust bindings, which are disabled
for now in the build, due to limited support, but coming in through
this tree due to dependencies on other rust binding changes that
were in here. I'll be enabling these back on in the build in the
usb.git tree after -rc1 is out so that developers can continue to
work on these in linux-next over the next development cycle.
- Android Binder driver implemented in Rust.
This is the big one, and was driving a huge majority of the rust
binding work over the past years. Right now there are two binder
drivers in the kernel, selected only at build time as to which one
to use as binder wants to be included in the system at boot time.
The binder C maintainers all agreed on this, as eventually, they
want the C code to be removed from the tree, but it will take a few
releases to get there while both are maintained to ensure that the
rust implementation is fully stable and compliant with the existing
userspace apis.
All of these have been in linux-next for a while"

Pull networking updates from Paolo Abeni:
"Core & protocols:
- Improve drop account scalability on NUMA hosts for RAW and UDP
sockets and the backlog, almost doubling the Pps capacity under DoS
- Optimize the UDP RX performance under stress, reducing contention,
revisiting the binary layout of the involved data structs and
implementing NUMA-aware locking. This improves UDP RX performance
by an additional 50%, even more under extreme conditions
- Add support for PSP encryption of TCP connections; this mechanism
has some similarities with IPsec and TLS, but offers superior HW
offloads capabilities
- Ongoing work to support Accurate ECN for TCP. AccECN allows more
than one congestion notification signal per RTT and is a building
block for Low Latency, Low Loss, and Scalable Throughput (L4S)
- Reorganize the TCP socket binary layout for data locality, reducing
the number of touched cachelines in the fastpath
- Refactor skb deferral free to better scale on large multi-NUMA
hosts, this improves TCP and UDP RX performances significantly on
such HW
- Increase the default socket memory buffer limits from 256K to 4M to
better fit modern link speeds
- Improve handling of setups with a large number of nexthop, making
dump operating scaling linearly and avoiding unneeded
synchronize_rcu() on delete
- Improve bridge handling of VLAN FDB, storing a single entry per
bridge instead of one entry per port; this makes the dump order of
magnitude faster on large switches
- Restore IP ID correctly for encapsulated packets at GSO
segmentation time, allowing GRO to merge packets in more scenarios
- Improve netfilter matching performance on large sets
- Improve MPTCP receive path performance by leveraging recently
introduced core infrastructure (skb deferral free) and adopting
recent TCP autotuning changes
- Allow bridges to redirect to a backup port when the bridge port is
administratively down
- Introduce MPTCP 'laminar' endpoint that con be used only once per
connection and simplify common MPTCP setups
- Add RCU safety to dst->dev, closing a lot of possible races
- A significant crypto library API for SCTP, MPTCP and IPv6 SR,
reducing code duplication
- Supports pulling data from an skb frag into the linear area of an
XDP buffer
Things we sprinkled into general kernel code:
- Generate netlink documentation from YAML using an integrated YAML
parser
Driver API:
- Support using IPv6 Flow Label in Rx hash computation and RSS queue
selection
- Introduce API for fetching the DMA device for a given queue,
allowing TCP zerocopy RX on more H/W setups
- Make XDP helpers compatible with unreadable memory, allowing more
easily building DevMem-enabled drivers with a unified XDP/skbs
datapath
- Add a new dedicated ethtool callback enabling drivers to provide
the number of RX rings directly, improving efficiency and clarity
in RX ring queries and RSS configuration
- Introduce a burst period for the health reporter, allowing better
handling of multiple errors due to the same root cause
- Support for DPLL phase offset exponential moving average,
controlling the average smoothing factor
Device drivers:
- Add a new Huawei driver for 3rd gen NIC (hinic3)
- Add a new SpacemiT driver for K1 ethernet MAC
- Add a generic abstraction for shared memory communication

Flush stale data from the RX FIFO in case of errors, to avoid reading
old data when new packets arrive.
Commit c6e8d85fafa7 ("staging: axis-fifo: Remove hardware resets for
user errors") removed full FIFO resets from the read error paths, which
fixed potential TX data losses, but introduced this RX issue.

If copy_from_user() fails, write() currently returns -EFAULT, but any
partially written data leaves the TX FIFO in an inconsistent state.
Subsequent write() calls then fail with "transmit length mismatch"
errors.
Once partial data is written to the hardware FIFO, it cannot be removed
without a TX reset. Commit c6e8d85fafa7 ("staging: axis-fifo: Remove
hardware resets for user errors") removed a full FIFO reset for this case,
which fixed a potential RX data loss, but introduced this TX issue.
Fix this by introducing a bounce buffer: copy the full packet from
userspace first, and write to the hardware FIFO only if the copy
was successful.

The use of 'volatile' for memory-mapped I/O pointers is discouraged
in the Linux kernel as per
Documentation/process/volatile-considered-harmful.rst.
This patch removes the unnecessary 'volatile' qualifiers from the
lynx_accel struct members, improving code quality and maintainability.

The PM usage counter of isys was bumped up when start camera stream
(opening firmware) but it was not dropped after stream stop(closing
firmware), it forbids system fail to suspend due to the wrong PM state
of ISYS. This patch drop the PM usage counter in firmware close to fix
it.
