Subject: misc: Convert to devm_ioremap_resource()
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=1684789f86cbd6a1aff82970992c711898b19995;p=linux-edison.git

misc: Convert to devm_ioremap_resource()

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.

devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.
