Subject: [PATCH v3 15/15] drm/shmem-helper: Remove drm_gem_shmem_purge()
Date:   Tue, 12 Apr 2022 00:59:37 +0300
Message-Id: <20220411215937.281655-16-dmitry.osipenko@collabora.com>
In-Reply-To: <20220411215937.281655-1-dmitry.osipenko@collabora.com>

The drm_gem_shmem_purge() was added back in 2019 and never had a user
since then. GEM's purging is now managed by the generic shrinker and
only the "locked" variant of the function is wanted. Remove the obsoleted
function.
