Subject: [PATCH v2 1/6] staging: rtl8723bs: replace deeply nested if-else with switch-case
Date: Mon, 23 Mar 2026 18:06:03 +0300 [thread overview]
Message-ID: <20260323150650.7168-2-nikolayof23@gmail.com> (raw)
In-Reply-To: <20260323150650.7168-1-nikolayof23@gmail.com>
The main logic of the validate_recv_mgnt_frame() function is deeply
nested due to multiple if-else statements and additional block scope.
Fix this by replacing identical if-else with switch-case statements,
which will improve code readability and correct checkpatch.pl warnings
about line lengths.
