However, pm_runtime_force_resume() won't really resume the codec because of pm_runtime_need_not_resume() check. Hence, hda_codec_force_resume() schedules a jackpoll work, which is to really power up the codec. Instead of doing that, we can use direct-complete to make the PM flow more straightforward, and keep codec always suspended through system PM flow if conditions are met. On system suspend, PM core will decide what to do based on hda_codec_pm_prepare(): - If codec is not runtime-suspended, PM core will suspend and resume the device as normal. - If codec is runtime-suspended, PM core will try to keep it suspended. If it's still suspended after system resume, we use hda_codec_pm_complete() to resume codec if it's needed.

High Definition Audio Specification, 4.5.9.3 Codec Wake From System S3 states that codec can wake the system up from S3 if WAKEEN is toggled. Since HDA controller has different wakeup settings for runtime and system susend, we also need to explicitly disable direct-complete which can be enabled automatically by PCI core. In addition to that, avoid waking up codec if runtime resume is for system suspend, to not break direct-complete for codecs. While at it, also remove AZX_DCAPS_SUSPEND_SPURIOUS_WAKEUP, as the original bug commit a6630529aecb ("ALSA: hda: Workaround for spurious wakeups on some Intel platforms") solves doesn't happen with this patch.
