Subject: [PATCH] mm/hmm: remove redundant variable align_end
Date: Tue, 17 Oct 2017 15:38:37 +0100 [thread overview]
Message-ID: <20171017143837.23207-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Variable align_end is assigned a value but it is never read, so
the variable is redundant and can be removed. Cleans up the clang
warning: Value stored to 'align_end' is never read
Signed-off-by: Colin Ian King <colin.king@canonical.com>
