Merge tag 'asoc-fix-v4.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound
Pull last-minute ASoC fix from Mark Brown: "This patch backs out a change that came in during the merge window which selects a configuration for GPIO4 on pcm512x CODECs that may not be suitable for all systems using the device. Changes for v4.1 will make this properly configurable but for now it's safest to revert to the v3.19 behaviour and leave the pin configuration alone. Sorry for sending this direct at the last minute but due to the GPIO misuse it'd be really good to get it in the release and I'd not realised it hadn't been sent yet - between some travel, a job change and other non-urgent fixes coming in I'd lost track of the urgency. It's been in -next for several weeks now, is isolated to the driver and fairly clear to inspection" * tag 'asoc-fix-v4.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound: ASoC: pcm512x: Remove hardcoding of pll-lock to GPIO4
