Merge tag 'asoc-fix-v4.15-rc4' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v4.15 This is a fairly large set of fixes, they've been delayed partly as more and more keep coming in. Most of them are very small driver specific fixes, the biggest individual thing is the revert of the rcar IOMMU support - it was causing problems and there wasn't the confidence that it could be resolved sensibly. There's also a relatively large change in the Freescale SSI controller which resolves some issues with the AC'97 mode, these aren't that large in the grand scheme of things and reflect some fairly thorough review and testing.
