Subject: [PATCH] iommu/arm-smmu: remove redundant assignment to variable res
Date: Fri, 25 Feb 2022 09:32:05 +0000 [thread overview]
Message-ID: <20220225093205.170973-1-colin.i.king@gmail.com> (raw)
The variable res is being assigned a value that isn't being read
later. The assignment is redundant and can be removed.
Cleans up clang scan warning:
drivers/iommu/arm/arm-smmu/arm-smmu.c:2109:10: warning: Although the
value stored to 'res' is used in the enclosing expression, the value
is never actually read from 'res' [deadcode.DeadStores]
