Subject: [PATCH] spi: clps711x: Provide label argument for devm_gpio_request
Date: Tue, 04 Mar 2014 12:59:53 +0800	[thread overview]
Message-ID: <1393909193.18753.1.camel@phoenix> (raw)

The label argument was removed by commit 989847967cd762
spi: clps711x: Use devm_gpio_request(), add it back.
This makes it easier to know the gpio usage in /sys/kernel/debug/gpio.

Also remove unnecessary gpio_is_valid() checking, devm_gpio_request() returns
error if the requested gpio is invalid.
