Subject: [PATCH] iommu/amd: remove unused variable flush_addr
Date: Sun, 22 Oct 2017 13:49:45 +0200 [thread overview]
Message-ID: <20171022114945.1479-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Variable flush_addr is being assigned but is never read; it
is redundant and can be removed. Cleans up the clang warning:
drivers/iommu/amd_iommu.c:2388:2: warning: Value stored to 'flush_addr'
is never read
Signed-off-by: Colin Ian King <colin.king@canonical.com>
