From: Sachin Kamat Date: Mon, 15 Apr 2013 20:38:07 +0000 (-0700) Subject: Input: apbps2 - convert to devm_ioremap_resource() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e07a8943b809730220a4aff911d2bce6991828f1;p=openwrt%2Fstaging%2Fblogic.git Input: apbps2 - 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.
