Subject: [PATCH] pwm: Remove a redundant error message when devm_request_and_ioremap fails
Date: Fri, 03 Aug 2012 21:43:54 +0800 [thread overview]
Message-ID: <1344001434.25906.5.camel@phoenix> (raw)
The implementation in devm_request_and_ioremap() already shows error message,
so no need to show dev_err again if devm_request_and_ioremap() fails.
