Subject: [PATCH] IB/hfi1: Remove redundant variable rcd
Date:   Sun, 25 Apr 2021 18:31:36 +0800
Message-Id: <1619346696-46300-1-git-send-email-jiapeng.chong@linux.alibaba.com>
Precedence: bulk

Variable rcd is being assigned a value from a calculation
however the variable is never read, so this redundant variable
can be removed.

Cleans up the following clang-analyzer warning:

drivers/infiniband/hw/hfi1/affinity.c:986:3: warning: Value stored to
'rcd' is never read [clang-analyzer-deadcode.DeadStores].
