staging: most: dim2: use device release method

2021-12-17T09:14:40+00:00

commit d445aa402d60014a37a199fae2bba379696b007d upstream.

Commit 723de0f9171e ("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.

staging: most: dim2: do not double-register the same device

2021-11-18T13:04:18+00:00

[ Upstream commit 2ab189164056b05474275bb40caa038a37713061 ]

Commit 723de0f9171e ("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.

staging: most: sound: add sanity check for function argument

2021-03-07T11:34:10+00:00

[ Upstream commit 45b754ae5b82949dca2b6e74fa680313cefdc813 ]

This patch checks the function parameter 'bytes' before doing the
subtraction to prevent memory corruption.

staging: most: dim2: Add missing identifier name to function argument

2020-08-18T13:56:27+00:00

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.

Merge tag 'staging-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

2020-08-06T21:36:13+00:00

Pull staging/IIO driver updates from Greg KH:
 "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"

When moving the most usb driver out of staging, we forgot to remove the
subdirectory out of the staging Makefile as well.

treewide: Replace DECLARE_TASKLET() with DECLARE_TASKLET_OLD()

2020-07-30T18:15:58+00:00

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.
