Subject: [PATCH AUTOSEL 6.6 08/40] bcache: remove redundant assignment to variable cur_idx
Date: Tue, 28 Nov 2023 16:05:14 -0500 [thread overview]
Message-ID: <20231128210615.875085-8-sashal@kernel.org> (raw)
In-Reply-To: <20231128210615.875085-1-sashal@kernel.org>
From: Colin Ian King <colin.i.king@gmail.com>
[ Upstream commit be93825f0e6428c2d3f03a6e4d447dc48d33d7ff ]
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]
