[PATCH v2 0/2] staging: sm750fb: Remove unused return values from functions

[Dorcas AnonoLitunya]

Modifies the return type of different static functions to void and
deletes unused return variables as the return value is being ignored 
in all subsequent function calls thus not useful to have a return type.

This improves code readability and maintainability.

Changes in v2:
- Ammend wording in cover letter.
Suggested-by: Julia Lawall <julia.lawall@xxxxxxxx>
- Drop variable 'ret' entirely as it is unused.
Suggested-by: Julia Lawall <julia.lawall@xxxxxxxx>, Greg Kroah-Hartman
<gregkh@xxxxxxxxxxxxxxxxxxx>, Dan Carpenter <dan.carpenter@xxxxxxxxxx>
