Subject: [PATCH v3] staging: sm750fb: Remove unused return value in display_control_adjust_sm750le()
Date: Wed, 1 Nov 2023 18:21:34 +0300 [thread overview]
Message-ID: <20231101152137.10664-2-anonolitunya@gmail.com> (raw)
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.
Suggested-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
