The driver shall update the power state to D0i0 before sending a generic IPC. Power-related IPCs are the exception to the rule, they may be sent even when the power-state is D0i3 Signed-off-by: Rander Wang <rander.wang@intel.com> Reviewed-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Reviewed-by: Ranjani Sridharan <ranjani.sridharan@linux.intel.com> Reviewed-by: Péter Ujfalusi <peter.ujfalusi@linux.intel.com> Signed-off-by: Peter Ujfalusi <peter.ujfalusi@linux.intel.com> Link: https://lore.kernel.org/r/20230214103345.30669-4-peter.ujfalusi@linux.intel.com Signed-off-by: Mark Brown <broonie@kernel.org>
