Dropping the last reference to the internal struct device should be the
last thing we do so delete the device first and then uninit it which
also involves the final put_device().

It's possible that not all proxy entries will be set up when the device
gets removed so check if they are before trying to dereference members
which are still NULL. This can happen if some consumers never requested
their shared GPIOs.

We need to actually store the address of the GPIO lookup table in the
reference struct before we try to free it or - worse - dereference its
members.

Don't consider disabled devices when traversing the device-tree looking
for shared GPIOs. Even if they do share a phandle to a pin, they can
never be instantiated and request it.

Initializing automatic __free variables to NULL without need (e.g.
branches with different allocations), followed by actual allocation is
in contrary to explicit coding rules guiding cleanup.h:
"Given that the "__free(...) = NULL" pattern for variables defined at
the top of the function poses this potential interdependency problem the
recommendation is to always define and assign variables in one statement
and not group variable definitions at the top of the function when
__free() is used."
Code does not have a bug, but is less readable and uses discouraged
coding practice, so fix that by moving declaration to the place of
assignment.

In sas_register_phys(), if an error is triggered in the loop process, we

If scsi_dh_attached_handler_name() fails to allocate the handler name,
dm-multipath (its only caller) assumes there is no attached device
handler, and sets the device up incorrectly. Return an error pointer
instead, so multipath can distinguish between failure, success where
there is no attached device handler, or when the path device is not a
SCSI device at all.

Commit 08b12cda6c44 ("scsi: ufs: core: Switch to scsi_get_internal_cmd()")
accidentally introduced a deadlock in the frequency scaling code.
ufshcd_clock_scaling_unprepare() may submit a device management command
while SCSI command processing is blocked. The deadlock was introduced by
using the SCSI core for submitting device management commands
(scsi_get_internal_cmd() + blk_execute_rq()). Fix this deadlock by calling
blk_mq_unquiesce_tagset() before any device management commands are
submitted by ufshcd_clock_scaling_unprepare().

The Device Tree binding schema for the SpacemiT P1 PMIC defines the main
input supply property as "vin-supply", but the driver defines the supply
name for BUCK and ALDO regulators as "vcc".
This causes the regulator core to lookup for a non-existent "vcc-supply".
Rename the supply from "vcc" to "vin", to match the DT binding and ensure
that the regulators input supplies are correctly resolved.
After this change, the regulators supply hierarchy is correctly reported:

RTC_DRV_SPACEMIT_P1 is a subdevice of P1 and should depend on
MFD_SPACEMIT_P1 rather than selecting it directly. Using 'select'
does not always respect the parent's dependencies, so 'depends on'
is the safer and more correct choice.
Additionally, the default value depends on MFD_SPACEMIT_P1 rather
than ARCH_SPACEMIT.

someone really want it
New drivers:
- Samsung Exynos 8890 SoC support
- Samsung Exynos derived Axis Communications ARTPEC-9 SoC support.
These guys literally live next door to me, ARTPEC spells out "Axis

- Microchip pic64gx "gpio2" SoC support
- Microchip Polarfire "iomux0" SoC support
- CIX Semiconductors SKY1 SoC support
- Rockchip RK3506 SoC support

- A whole bunch of device tree binding cleanups: Marvell Armada and

Apple Silicon Macs (M1, etc.) have an RTC that is part of the PMU IC,
but most of the PMU functionality is abstracted out by the SMC.
On T600x machines, the RTC counter must be accessed via the SMC to
get full functionality, and it seems likely that future machines
will move towards making SMC handle all RTC functionality.
The SMC RTC counter access is implemented on all current machines
as of the time of this writing, on firmware 12.x. However, the RTC
offset (needed to set the time) is still only accessible via direct
PMU access. To handle this, we expose the RTC offset as an NVMEM
cell from the SPMI PMU device node, and this driver consumes that
cell and uses it to compute/set the current time.

Switch from devm_reset_control_get_shared() to
devm_reset_control_array_get_shared() when retrieving resets.
The RZ/V2H SoC requires two resets for the RTC block instead of one,
so this will allow to handle multiple resets without additional changes.

The register buffer in s35390a_get_reg() was previously defined as
`char *buf`. This is not ideal since register data represents raw
binary values rather than textual data.
Switch the type to `u8 *buf` to better reflect its intended usage and
to avoid potential issues with sign extension when handling register
values on platforms where `char` is signed by default.
This change improves type safety and makes the code consistent with
other RTC drivers that operate on raw register data.

Handling most of the ublksrv_ctrl_cmd opcodes require locking a mutex,
so ublk_ctrl_uring_cmd() bails out with EAGAIN when called with the
IO_URING_F_NONBLOCK issue flag. However, several opcodes can be handled
without blocking:
- UBLK_CMD_GET_QUEUE_AFFINITY
- UBLK_CMD_GET_DEV_INFO
- UBLK_CMD_GET_DEV_INFO2
- UBLK_U_CMD_GET_FEATURES
Handle these opcodes synchronously instead of returning EAGAIN so
io_uring doesn't need to issue the command via the worker thread pool.

On a 32-bit ARM system, the audio_decoder struct ends up being too large
for dp_retrain_link_dp_test.
link_dp_cts.c:157:1: error: the frame size of 1328 bytes is larger than
1280 bytes [-Werror=frame-larger-than=]
This is mitigated by shrinking the members of the struct and avoids
having to deal with dynamic allocation.
feed_back_divider is assigned but otherwise unused. Remove both.
pixel_repetition looks like it should be a bool since it's only ever
assigned to 1. But there are checks for 2 and 4. Reduce to uint8_t.

[WHAT]
When compiling Linux kernel with clang, the following warning / error
messages pops up:
drivers/gpu/drm/amd/amdgpu/../dal-dev/dc/dml2_0/display_mode_core.c:6853:12:
error: stack frame size (2120) exceeds limit (2056) in

*mode_lib)
[HOW]
Refactoring CalculateVMRowAndSwath_params assignments to a new function
helps reduce the stack frame size in dml_core_mode_support.

The trap may be entered with dependency checking disabled.
Wait for dependency counters and save/restore scheduling mode.
v2:
Use ttmp1 instead of ttmp11. ttmp11 is not zero-initialized.
While the trap handler does zero this field before use, a user-mode
second-level trap handler could not rely on this being zero when
using an older kernel mode driver.
v3:
Use ttmp11 primarily but copy to ttmp1 before jumping to the
second level trap handler. ttmp1 is inspectable by a debugger.
Unexpected bits in the unused space may regress existing software.

No functional change for now, but this struct will have more
fields added in the next commit.
This change would introduce synchronisation issue, because
dependencies between successive jobs are not taken care of
properly. For instance, amdgpu_ttm_clear_buffer uses
amdgpu_ttm_map_buffer then amdgpu_ttm_fill_mem which should
use different entities (default_entity then move/clear entity).
To prevent failures for this commit, we limit ourselves to
2 entities: default_entity (which replaces high_pr usages) and
clear_entity (which replaces low_pr usages).
The next commits will deal with these dependencies correctly,
and then we'll be able to use move_entity.
