X-Git-Tag: v4.0~1536^2~2415
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f2b4dc1a0fc8f52e06025497ce9bb252ff51f15f;p=platform%2Fkernel%2Flinux-amlogic.git

[media] sh_veu.c: Convert to devm_ioremap_resource()

Use the newly introduced devm_ioremap_resource() instead of
devm_request_and_ioremap() which provides more consistent error handling.
