Subject: [PATCH][next] bcache: remove redundant assignment to variable cur_idx
Date: Tue, 25 Jul 2023 12:46:37 +0100 [thread overview]
Message-ID: <20230725114637.37073-1-colin.i.king@gmail.com> (raw)
Variable cur_idx is being initialized with a value that is never read,
it is being re-assigned later in a while-loop. Remove the redundant
assignment. Cleans up clang scan build warning:
drivers/md/bcache/writeback.c:916:2: warning: Value stored to 'cur_idx'
is never read [deadcode.DeadStores]
