Subject: [PATCH 1/2] staging: sm750fb: Remove unused return value in display_control_adjust_sm750le()

Modifies the return type of display_control_adjust_sm750le()
to void from unsigned long as the return value is being ignored in
all subsequent function calls.

This improves code readability and maintainability.
