Subject: [PATCH 09/11] drm/vmwgfx: Stop checking for DRM_UNLOCKED
Date: Tue, 8 Sep 2015 13:56:29 +0200 [thread overview]
Message-ID: <1441713391-24732-10-git-send-email-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <1441713391-24732-1-git-send-email-daniel.vetter@ffwll.ch>
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.
