Subject: [PATCH] net: macb: Remove redundant assignment to queue
Date: Thu, 29 Apr 2021 18:25:46 +0800 [thread overview]
Message-ID: <1619691946-90305-1-git-send-email-jiapeng.chong@linux.alibaba.com> (raw)
Variable queue is set to bp->queues but these values is not used as it
is overwritten later on, hence redundant assignment can be removed.
Cleans up the following clang-analyzer warning:
drivers/net/ethernet/cadence/macb_main.c:4919:21: warning: Value stored
to 'queue' during its initialization is never read
[clang-analyzer-deadcode.DeadStores].
drivers/net/ethernet/cadence/macb_main.c:4832:21: warning: Value stored
to 'queue' during its initialization is never read
[clang-analyzer-deadcode.DeadStores].
