From afb5a7793144179bfd856e3c928b69c43e2a1d8a Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sat, 26 Oct 2013 00:33:58 +0200 Subject: ALSA: hda - Sync EAPD with vmaster on AD1984A Thinkpads As EAPD on NID 0x12 (speaker pin) is used as the master amp on Thinkpads with AD1984A codec, we can hook this to vmaster for saving a bit more power at master mute state.
