HID: amd_sfh: Add support for shutdown operation
As soon as the system is booted after shutdown, the sensors may remain in a weird state and fail to initialize. Therefore, all sensors should be turned off during shutdown. Fixes: 4f567b9f8141 ("SFH: PCIe driver to add support of AMD sensor fusion hub") Signed-off-by: Basavaraj Natikar <Basavaraj.Natikar@amd.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
