This update for plymouth provides the following fixes:

- Make sure plymouthd stops throbber animation at the first opportunity after receiving
quit command, instead of looping multiple times. (bsc#1110199)
- drm: Use preferred mode for outputs.
- drm: Refactor ply_renderer_connector_get_rotation.
- drm: Reset LUT/gamma table before the first drmModeSetCrtc call.
- libply: Move kernel command line parsing functions to libply/ply-utils.
- throbber: Don't skip last frame when waiting for end.
- systemd-units: Add "ConditionVirtualization=!container" in systemd-ask-password-plymouth.path.
