Subject: [PATCH 3/7] block: drbd: drbd_receiver: Remove redundant assignment to err
From: Jiapeng Chong <jiapeng.chong@...ux.alibaba.com>
Variable err is set to '-EIO' but this value is never read as
it is overwritten or not used later on, hence it is a redundant
assignment and can be removed.
Clean up the following clang-analyzer warning:
drivers/block/drbd/drbd_receiver.c:3955:5: warning: Value stored to
'err' is never read [clang-analyzer-deadcode.DeadStores].
