Merge tag 'sound-3.18-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound fixes from Takashi Iwai: "This update contains mostly only fixes for Realtek HD-audio codec driver in addition to a long-standing sysfs warning bug fix for USB-audio. One significant fix for Realtek codecs is the update of EAPD init codes. This avoids invalid COEF setups for some codec models and may fix "lost sound" in some cases. The rest are a bit high volume but only new quirks and ALC668-specific COEF tables" * tag 'sound-3.18-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ALSA: hda/realtek - Restore default value for ALC668 ALSA: usb-audio: Fix device_del() sysfs warnings at disconnect ALSA: hda - fix mute led problem for three HP laptops ALSA: hda/realtek - Update Initial AMP for EAPD control ALSA: hda - change three SSID quirks to one pin quirk ALSA: hda - Set GPIO 4 low for a few HP machines ALSA: hda - Add ultra dock support for Thinkpad X240.
