From ecac3ed174034755ebc0b29393fb501ffd0b2afc Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 21 Dec 2012 15:23:01 +0100 Subject: [PATCH] ALSA: hda - Add inv_eapd flag to struct hda_codec Add the new flag, codec->inv_eapd, indicating that the EAPD implementation is inverted. There are always broken hardware in the world.
