Subject: [PATCH][next] fs/direct-io: remove redundant assignment to variable retval
Date: Wed, 10 Apr 2024 17:22:21 +0100 [thread overview]
Message-ID: <20240410162221.292485-1-colin.i.king@gmail.com> (raw)
The variable retval is being assigned a value that is not being read,
it is being re-assigned later on in the function. The assignment
is redundant and can be removed.
Cleans up clang scan build warning:
fs/direct-io.c:1220:2: warning: Value stored to 'retval' is never
read [deadcode.DeadStores]
