Merge tag 'asoc-fix-v4.0-rc7' into asoc-linus
ASoC: Last minute fix for v4.0 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. # gpg: Signature made Sat 11 Apr 2015 22:14:17 BST using RSA key ID 5D5487D0 # gpg: WARNING: digest algorithm MD5 is deprecated # gpg: please see https://gnupg.org/faq/weak-digest-algos.html for more information # gpg: Oops: keyid_from_fingerprint: no pubkey # gpg: Good signature from "Mark Brown <broonie@sirena.org.uk>" # gpg: aka "Mark Brown <broonie@debian.org>" # gpg: aka "Mark Brown <broonie@kernel.org>" # gpg: aka "Mark Brown <broonie@tardis.ed.ac.uk>" # gpg: aka "Mark Brown <broonie@linaro.org>" # gpg: aka "Mark Brown <Mark.Brown@linaro.org>"
