From d02117f8efaa5fbc37437df1ae955a147a2a424a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Christian=20K=C3=B6nig?= Date: Sat, 17 Apr 2021 19:09:30 +0200 Subject: [PATCH] drm/ttm: remove special handling for non GEM drivers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit vmwgfx is the only driver actually using this. Move the handling into the driver instead.
