Subject: [PATCH] udf: remove unused variables group_start and nr_groups
Date: Wed, 29 Aug 2018 11:16:12 +0100	[thread overview]
Message-ID: <20180829101612.31824-1-colin.king@canonical.com> (raw)

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

Variables group_start and nr_groups are being assigned but are never used
hence they are redundant and can be removed.

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