Subject: [PATCH 6/9] drm/nouveau: stop implementing init_mem_type
Date: Thu, 23 Jul 2020 17:17:07 +0200	[thread overview]
Message-ID: <20200723151710.3591-7-christian.koenig@amd.com> (raw)
In-Reply-To: <20200723151710.3591-1-christian.koenig@amd.com>

Instead just initialize the memory type parameters
before calling ttm_bo_init_mm.
