Subject: [PATCH] dmaengine: idxd: Remove redundant variable cdev_ctx
Date: Thu, 6 May 2021 19:00:47 +0800 [thread overview]
Message-ID: <1620298847-33127-1-git-send-email-jiapeng.chong@linux.alibaba.com> (raw)
Variable cdev_ctx is set to '&ictx[wq->idxd->data->type]' but this
value is not used, hence it is a redundant assignment and can be
removed.
Clean up the following clang-analyzer warning:
drivers/dma/idxd/cdev.c:300:2: warning: Value stored to 'cdev_ctx' is
never read [clang-analyzer-deadcode.DeadStores].
