From: Takashi Iwai <tiwai@xxxxxxx> commit 8c2fa44132e8cd1b05c77a705adb8d1f5a5daf3f upstream. It was reported that the headphone output on Dell Venue 11 Pro 7130 becomes mono after PM resume. The cause seems to be the BIOS setting up the codec COEF 0x0d bit 0x40 wrongly by some reason, and restoring the original value 0x2800 fixes the problem. This patch adds the quirk entry to perform the COEF restore.
