Subject: [PATCH v2] ASoC: uda1380: Convert to gpio_request_one()
Date: Mon, 05 Dec 2011 07:58:25 +0800 [thread overview]
Message-ID: <1323043105.5179.1.camel@phoenix> (raw)
Using gpio_request_one can make the error handling simpler.
Also remove a redundant "Failed to issue reset" error message.
We already show the error message in uda1380_reset() error path.
