drm/mgag200: Extract device type from flags
Adds a conversion function that extracts the device type from the PCI id-table flags. Allows for storing additional information in the other flag bits. Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Fixes: 81da87f63a1e ("drm: Replace drm_gem_vram_push_to_system() with kunmap + unpin") Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: John Donnelly <john.p.donnelly@oracle.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Dave Airlie <airlied@redhat.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: David Airlie <airlied@linux.ie> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Emil Velikov <emil.velikov@collabora.com> Cc: "Y.C.
