Subject: [PATCH v5 16/17] drm/shmem-helper: Make drm_gem_shmem_is_purgeable() private
Date:   Sun, 24 Apr 2022 22:04:23 +0300
Message-Id: <20220424190424.540501-17-dmitry.osipenko@collabora.com>
In-Reply-To: <20220424190424.540501-1-dmitry.osipenko@collabora.com>

Panfrost driver was the only user of the drm_gem_shmem_is_purgeable()
helper. Panfrost driver was converted to use new generic memory shrinker
and the helper doesn't have external users anymore, hence make it private
to the drm_gem_shmem_helper.c to keep the code clean.
