Subject: [PATCH 9/9] drm/ttm: remove the init_mem_type callback
Date: Thu, 30 Jul 2020 11:00:15 +0200	[thread overview]
Message-ID: <20200730090015.17295-9-christian.koenig@amd.com> (raw)
In-Reply-To: <20200730090015.17295-1-christian.koenig@amd.com>

It is a very strange concept to call a function which just
calls back the caller for the functions parameters.
