Subject: [PATCH 03/10] bcache: remove redundant assignment to variable cur_idx
Date: Mon, 20 Nov 2023 13:24:56 +0800	[thread overview]
Message-ID: <20231120052503.6122-4-colyli@suse.de> (raw)
In-Reply-To: <20231120052503.6122-1-colyli@suse.de>

From: Colin Ian King <colin.i.king@gmail.com>

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]
