gpiochip_get_direction(). Remove the duplicated check which also returns

It's strongly recommended for GPIO drivers to always implement the
.get_direction() callback - even for fixed-direction controllers.
GPIO core will even emit a warning if the callback is missing, when
users try to read the direction of a pin.
Implement .get_direction() for gpio-davinci.

The header files generated by dot2c currently create enums for states
and events assigning the first element to 0. This is superfluous as it
happens automatically if no value is specified.
Also it doesn't add a comma to the last enum elements, which slightly
complicates the diff if states or events are added.
Remove the assignment to 0 and add a comma to last elements, this
simplifies the logic for the code generator.

Previous changes refactored the da_monitor header file to avoid using
macros, however empty macros (e.g. DECLARE_DA_FUNCTION) were left to
ease review with diff tools.
Most macros also get the argument type which doesn't really have a
purpose since states have their own enum and the storage in struct
da_monitor is fixed to unsigned int.
Remove empty and no longer required macros and substitute the type
parameter with the appropriate enum.
Additionally break long line and adjust the format overall.

The da_monitor helper functions are generated from macros of the type:
DECLARE_DA_FUNCTION(name, type) \
static void da_func_x_##name(type arg) {} \
static void da_func_y_##name(type arg) {} \
This is good to minimise code duplication but the long macros made of
skipped end of lines is rather hard to parse. Since functions are
static, the advantage of naming them differently for each monitor is
minimal.
Refactor the da_monitor.h file to minimise macros, instead of declaring
functions from macros, we simply declare them with the same name for all
monitors (e.g. da_func_x) and for any remaining reference to the monitor
name (e.g. tracepoints, enums, global variables) we use the CONCATENATE
macro.
In this way the file is much easier to maintain while keeping the same
generality.
Functions depending on the monitor types are now conditionally compiled
according to the value of RV_MON_TYPE, which must be defined in the
monitor source.
The monitor type can be specified as in the original implementation,
although it's best to keep the default implementation (unsigned char) as
not all parts of code support larger data types, and likely there's no
need.
We keep the empty macro definitions to ease review of this change with
diff tools, but cleanup is required.
Also adapt existing monitors to keep the build working.

scsi_host_busy() iterates over the host tag set. The host tag set is
initialized by scsi_mq_setup_tags(). The latter function is called by

has been added. This patch prepares for reverting commit a0b7780602b1

1394 OHCI PCI driver had long been the only user of dma_alloc_pages().
Although tee subsystem recently started using it, they are still a few
users of the infrequently-used function.
In the discussion for dma-mapping function, Jason Gunthorpe shows his
opinion about the design of public API for the function. According to it,
the users provide physical address to the function, then receive DMA
mapping address, regardless of the location of mapping target.
With the above aspects, this commit eliminates the use of
dma_alloc_pages() from this subsystem.

This is supposed to test for integer overflow but it is wrong and
unnecessary. The size_add()/mul() macros return SIZE_MAX when there is
an integer overflow. This code saves the SIZE_MAX to a u64 and then
tests if the result is greater than SIZE_MAX which it never will be.
Fortunately, when we try to allocate SIZE_MAX bytes the allocation
will fail. We even pass __GFP_NOWARN so the allocation fails
harmlessly and quietly.

Uwe Kleine-König <u.kleine-koenig@baylibre.com> says:
Hello,
this is v2 of the series to make the scsi subsystem stop using the
callbacks .probe(), .remove() and .shutdown() of struct device_driver.
Instead use their designated alternatives in struct bus_type.
The eventual goal is to drop the callbacks from struct device_driver.
The 2nd patch introduces some legacy handling for drivers still using
the device_driver callbacks. This results in a runtime warning (in
driver_register()). The following patches convert all in-tree drivers
(and thus fix the warnings one after another).
Conceptually this legacy handling could be dropped at the end of the
series, but I think this is a bad idea because this silently breaks
out-of-tree drivers (which also covers drivers that are currently
prepared for mainline submission) and in-tree drivers I might have
missed (though I'm convinced I catched them all). That convinces me that
keeping the legacy handling for at least one development cycle is the
right choice. I'll care for that at the latest when I remove the
callbacks from struct device_driver.

Introduce a bus-specific probe, remove and shutdown function. For now
this only allows to get rid of a cast of the generic device to a SCSI
device in the drivers and changes the remove prototype to return
void---a non-zero return value is ignored anyhow.
The objective is to get rid of users of struct device_driver callbacks
.probe(), .remove() and .shutdown() to eventually remove these. Until
all SCSI drivers are converted, this results in a runtime warning about
the drivers needing an update because there is a bus probe function and
a driver probe function. The in-tree drivers are fixed by the following
commits.

In `probe()`, `request_irq()` is called before allocating/registering a
`power_supply` handle. If an interrupt is fired between the call to
`request_irq()` and `power_supply_register()`, the `power_supply` handle
will be used uninitialized in `power_supply_changed()` in
`wm97xx_bat_update()` (triggered from the interrupt handler). This will
lead to a `NULL` pointer dereference since
Fix this racy `NULL` pointer dereference by making sure the IRQ is
requested _after_ the registration of the `power_supply` handle. Since
the IRQ is the last thing requests in the `probe()` now, remove the
error path for freeing it. Instead add one for unregistering the
`power_supply` handle when IRQ request fails.

Commit 5bff79dad20a ("power: supply: Add bd718(15/28/78) charger driver")
adds the file bd71828-power.c in drivers/power/supply/, whereas commit
b838cecc2291 ("MAINTAINERS: Add entry for BD71828 charger") from the same
patch series, adds a section referring to the non-existing file
bd71828-charger.c in the directory above.
Adjust the file entry to refer to the intended existing file.

Memory pointer by pointer passed to dev_attr_psp() is not modified, so
with help of container_of_const() (preferred than container_of()) can be
made pointer to const for code safety.
