Subject: [media] soc_camera/pxa_camera: Convert to devm_ioremap_resource()
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=8efdb13543909af277a93bab17730e92b552b7c9;p=linux-edison.git

[media] soc_camera/pxa_camera: Convert to devm_ioremap_resource()

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