soundwire: bus: update Slave status in sdw_clear_slave_status
Call to sdw_update_slave_status() needs to be added to sdw_clear_slave_ status() to ensure Slaves are informed of the new status via update_ status() callback. This will enable codec drivers to reset their internal states and make sure the register settings are properly restored on pm_runtime or system resume BugLink: https://github.com/thesofproject/linux/issues/2908 BugLink: https://github.com/thesofproject/linux/issues/2637 Signed-off-by: Bard Liao <yung-chuan.liao@linux.intel.com> Reviewed-by: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com> Link: https://lore.kernel.org/r/20210714033609.11963-1-yung-chuan.liao@linux.intel.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
