Subject: [PATCH 21/33] pinctrl: Convert to devm_ioremap_resource()
Date: Mon, 21 Jan 2013 11:09:14 +0100	[thread overview]
Message-ID: <1358762966-20791-22-git-send-email-thierry.reding@avionic-design.de> (raw)
In-Reply-To: <1358762966-20791-1-git-send-email-thierry.reding@avionic-design.de>

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.
