Subject: ASoC: io: Remove support for ASoC cache in conjunction with regmap
X-Git-Tag: v3.15-rc1~36^2~1^2~3^2~3^3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=657254714ad2ba69b73fcb02f0b1db378b1f220e;p=platform%2Fkernel%2Flinux-exynos.git

ASoC: io: Remove support for ASoC cache in conjunction with regmap

Since all regmap CODECs should be (and are) using the more advance regmap
cache infrastructure remove the code which supports that and just proxy
I/O straight through to regmap.
