From 87698c8aa77ce58c41a09b72a0c35fdbc9949025 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 8 Sep 2015 13:56:29 +0200 Subject: [PATCH] drm/vmwgfx: Stop checking for DRM_UNLOCKED drm core enforces now for DRIVER_MODESET that all ioctls are unlocked. And all the old nasty ones from drm core aren't allowed for modern drivers any more. Hence this is no longer needed.
