Subject: Thermal: kirkwood: Convert to devm_ioremap_resource()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=aa3b5d222da5922ab1883eba3e9d8f92ad148155;p=linux-beck.git

Thermal: kirkwood: Convert to devm_ioremap_resource()

Use the newly introduced devm_ioremap_resource() instead of
devm_request_and_ioremap() 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.
