Subject: [PATCH] fscache, cachefiles: remove redundant pointer 'cache'
Date: Tue, 17 Jul 2018 09:53:42 +0100	[thread overview]
Message-ID: <20180717085342.17864-1-colin.king@canonical.com> (raw)

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

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

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