From 58cb138e20296dffe3b2be2beb64e5aa22846b84 Mon Sep 17 00:00:00 2001 From: Jiapeng Chong Date: Thu, 6 May 2021 19:00:47 +0800 Subject: [PATCH] dmaengine: idxd: Remove redundant variable cdev_ctx 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].
