[PATCH v4 00/23] staging: r8188eu: remove unneeded ret variables

[Abdun Nihaal <abdun.nihaal@gmail.com>]

This patchset does the following to functions in ioctl_linux.c:
- Remove unneeded return variable in some functions.
  These functions cannot be converted to void either because it is an
  iw_handler function or the function does return error code.
- Propagate error code in rtw_p2p_get2 function
- Convert some functions that always return 0 to return void

v3 -> v4:
- Split the changes into smaller patches to make it easier to review
- Add a new patch to propagate error code in rtw_p2p_get2 function

v2 -> v3:
- Remove returns at the end of void functions to conform to coding style

v1 -> v2:
- As suggested by Greg, change functions that always return 0
  and whose return value is not used, to return void instead.
- Not removing return variables in rtw_p2p_get2 and rtw_p2p_set
  as they may need to be used.
