Subject: [PATCH][next] ALSA: echoaudio: remove redundant assignment to variable clock
Date: Wed, 21 Feb 2024 11:38:09 +0000 [thread overview]
Message-ID: <20240221113809.3410109-1-colin.i.king@gmail.com> (raw)
The variable clock is being assigned a value that is never read,
it is being re-assigned a new value in every case in the following
switch statement. The assignment is redundant and can be removed.
Cleans up clang scan build warning:
sound/pci/echoaudio/echoaudio_3g.c:277:2: warning: Value stored
to 'clock' is never read [deadcode.DeadStores]
