[PATCH 01/13] Input: keyboard - Drop calls to platform_set_drvdata and i2c_set_clientdata

[PATCH 01/13] Input: keyboard - Drop calls to platform_set_drvdata and i2c_set_clientdata

[Guenter Roeck]

There is no call to i2c_get_clientdata(), platform_get_drvdata(),
or dev_get_drvdata() in any of the drivers in this patch.
Drop the unnecessary calls to to i2c_set_clientdata() and
platform_set_drvdata().

This conversion was done automatically with coccinelle. The semantic patch
is available at
https://github.com/groeck/coccinelle-patches/blob/master/common/pdev.cocci

[PATCH 10/13] Input: misc - drop unnecessary calls to device_init_wakeup

[Guenter Roeck]

Calling device_init_wakeup in the remove function is unnecessary since the
device is going away, and thus won't be able to cause any wakeups under any
circumstances. Besides, the driver cleanup code already handles the
necessary cleanup.

Similar, disabling wakeup in the probe error path is unnecessary, as is

[PATCH 13/13] Input: misc - drop empty remove functions

[Guenter Roeck]

Empty remove functions don't serve a useful purpose and can be removed.

Changes were made using the following coccinelle script.

@remove@
identifier p, removefn;
@@

  struct platform_driver p = {
    .remove = \(__exit_p(removefn)\|removefn\),
  };

@rrem depends on remove@
identifier remove.removefn;
@@

- removefn(...) {
- return 0;
- }

@depends on rrem@
identifier remove.p, remove.removefn;
@@

struct platform_driver p = {
- .remove = \(__exit_p(removefn)\|removefn\),
};
