v2 cover staging: r8188eu: remove unneeded ret variables

This patchset removes unneeded return variables in ioctl_linux.c, and also converts functions that always return 0 to return void.

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.
These functions call other functions that do return error codes (mostly -1 and -EFAULT) but are not propagated back. I'll send a different patch to fix that.

PATCH v2 1/2 staging: r8188eu: remove unneeded ret variables

Remove unneeded return variables in ioctl_linux.c that are initialized to 0 and are not assigned after. Instead, return 0 directly.

Found using coccinelle (returnvar.cocci).

v1 -> v2:
Not removing unneeded return variable in rtw_p2p_get2 and rtw_p2p_set because they have to be used.

PATCH v2 2/2 staging: r8188eu: change functions to return void

In reply to Abdun Nihaal

Some functions in ioctl_linux.c always returns 0 and their return values are never used. Change return type of such functions to void.

While at it, align function arguments with open parenthesis to fix checkpatch checks.

Re: [PATCH v2 2/2] staging: r8188eu: change functions to return void

Quoted 316 lines · Abdun Nihaal

Some functions in ioctl_linux.c always returns 0 and their return values are never used. Change return type of such functions to void.

While at it, align function arguments with open parenthesis to fix checkpatch checks.

Some functions in ioctl_linux.c always returns 0 and their return values are never used. Change return type of such functions to void.
While at it, align function arguments with open parenthesis to fix checkpatch checks.

Yes, I ran checkpatch on both the patches and found no errors, warnings or checks. Is there something that needs to be fixed?

You're not allowed to end a void function with a return statement.

Checkpatch will only detect these if you run it again with the -f option.

Sorry, I didn't know that. I'll fix it.

Thanks. I'll make sure to run checkpatch on the modified files also (not just on the patches).
