[PATCH] drivers: usb: chipidea: convert to devm_ioremap_resource()

From: Silviu-Mihai Popescu
Date: Wed Apr 10 2013 - 17:05:44 EST


Convert use 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.
