Lukas Wunner 009f8c90f5 ALSA: hda - Fix runtime PM ... Before commit 3b5b899ca6 ("ALSA: hda: Make use of core codec functions to sync power state"), hda_set_power_state() returned the response to the Get Power State verb, a 32-bit unsigned integer whose expected value is 0x233 after transitioning a codec to D3, and 0x0 after transitioning it to D0. The response value is significant because hda_codec_runtime_suspend() does not clear the codec's bit in the codec_powered bitmask unless the AC_PWRST_CLK_STOP_OK bit (0x200) is set in the response value. That in turn prevents the HDA controller from runtime suspending because azx_runtime_idle() checks that the codec_powered bitmask is zero. Since commit 3b5b899ca6, hda_set_power_state() only returns 0x0 or 0x1, thereby breaking runtime PM for any HDA controller. That's because an inline function introduced by the commit returns a bool instead of a 32-bit unsigned int. The change was likely erroneous and resulted from copying and pasting snd_hda_check_power_state(), which is immediately preceding the newly introduced inline function. Fix it.
