drm/qxl: Use simple encoder
The qxl driver uses an empty implementation for its encoder. Replace the code with the generic simple encoder. v4: * handle errors returned from drm_simple_encoder_init() v2: * rebase onto new simple-encoder interface Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20200228081828.18463-5-tzimmermann@suse.de
