The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Tasklets have long been deprecated as being too heavy on the system
by running in irq context - and this is not a performance critical
path. If a higher priority process wants to run, it must wait for
the tasklet to finish before doing so. A more suitable equivalent
is to converted to threaded irq instead and service channels in
regular task context.

Here is the big set of staging driver updates for 5.18-rc1.
Loads of tiny cleanups for almost all staging drivers in here, nothing
major at all. Highlights include:
- remove the ashmem Android driver. It is long-dead and if
there are any legacy userspace applications still using it,
the Android kernel images will maintain it, the community
shouldn't care about it anymore
- wfx wifi driver major cleanups. Should be ready to merge out
of staging soon, and will coordinate with the wifi maintainers
after -rc1 is out
- major cleanups and unwinding of the layers of the r8188eu
driver. It's amazing just how many unneeded layers of
abstraction is in there, just when we think it's done, another
is found...
- lots of tiny coding style cleanups in many other staging
drivers.
There will be merge conflict with a fbtft change and the spi driver
changes in your tree, but it's pretty obvious what to do (the function
shouldn't return anything.)
All have been in linux-next for a while with no reported problems.

media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.
On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
1) enable Video4Linux and make its Kconfig options to appear;
2) it makes the Kernel build the V4L core.
while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.
With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.
At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:
menu "Video4Linux options"
visible if VIDEO_DEV
source "drivers/media/v4l2-core/Kconfig"
endmenu
but it doesn't affect anymore the V4L core drivers.
The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:
config VIDEO_V4L2
tristate
depends on (I2C || I2C=n) && VIDEO_DEV
select RATIONAL
select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
default (I2C || I2C=n) && VIDEO_DEV
In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.
Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.

Commit 723de0f917 ("staging: most: remove device from interface
structure") moved registration of driver-provided struct device to
the most subsystem. This updated dim2 driver as well.
However, struct device passed to register_device() becomes refcounted,
and must not be explicitly deallocated, but must provide release method
instead. Which is incompatible with managing it via devres.
This patch makes the device structure allocated without devres, adds
device release method, and moves device destruction there.

Commit 723de0f917 ("staging: most: remove device from interface
structure") moved registration of driver-provided struct device to
the most subsystem.
Dim2 used to register the same struct device to provide a custom device
attribute. This causes double-registration of the same struct device.
Fix that by moving the custom attribute to driver's dev_groups.
This moves attribute to the platform_device object, which is a better
location for platform-specific attributes anyway.

A function definition argument should have an identifier name according
to checkpatch:
WARNING: function definition argument 'struct platform_device *' should
also have an identifier name
Name it pdev as that name is already used throughout the code.

Here is the large set of Staging and IIO driver patches for 5.9-rc1.
Lots of churn here, but overall the size increase in lines added is
small, while adding a load of new IIO drivers.
Major things in here:
- lots and lots of IIO new drivers and frameworks added
- IIO driver fixes and updates
- lots of tiny coding style cleanups for staging drivers
- vc04_services major reworks and cleanups
We had 3 set of drivers move out of staging in this round as well:
- wilc1000 wireless driver moved out of staging
- speakup moved out of staging
- most USB driver moved out of staging
Full details are in the shortlog.
All of these have been in linux-next with no reported issues. The last
few changes here were to resolve reported linux-next issues, and they
seem to have resolved the problems.

This converts all the existing DECLARE_TASKLET() (and ...DISABLED)
macros with DECLARE_TASKLET_OLD() in preparation for refactoring the
tasklet callback type. All existing DECLARE_TASKLET() users had a "0"
data argument, it has been removed here as well.

The interface pointer passed to a component API function cannot be NULL.
This patch removes the unnecessary sanity check of this argument.

This patch uses a less confusing list traversing structure to

Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'
