Subject: ALSA: hda/sigmatel: Keep power up while beep is enabled
From: Takashi Iwai <tiwai@xxxxxxx>
commit 414d38ba871092aeac4ed097ac4ced89486646f7 upstream.
It seems that the beep playback doesn't work well on IDT codec devices
when the codec auto-pm is enabled. Keep the power on while the beep
switch is enabled.
