Subject: [PATCH] xen/privcmd: remove unused variable pageidx
Date: Wed, 8 Nov 2017 13:00:30 +0000 [thread overview]
Message-ID: <20171108130030.25394-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Variable pageidx is assigned a value but it is never read, hence it
is redundant and can be removed. Cleans up clang warning:
drivers/xen/privcmd.c:199:2: warning: Value stored to 'pageidx'
is never read
