[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 = \(__exit_p(removefn)\|removefn\),
};
