Subject: [PATCH v2] pci: convert to devm_ioremap_resource()
Date: Tue, 12 Mar 2013 09:28:00 +0200	[thread overview]
Message-ID: <1363073281-9939-1-git-send-email-silviupopescu1990@gmail.com> (raw)

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.
