Subject: [PATCH] apparmor: remove redundant pointer 'info'
Date:   Sat, 14 Jul 2018 17:19:05 +0100

From: Colin Ian King <colin.king@canonical.com>

Pointer 'info' is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'info' set but not used [-Wunused-but-set-variable]
