Subject: [PATCH 7/9] backlight: atmel-pwm-bl: use gpio_is_valid
Date: Tue, 22 Oct 2013 17:26:57 +0000 [thread overview]
Message-ID: <1382462819-28576-8-git-send-email-jhovold@gmail.com> (raw)
In-Reply-To: <1382462819-28576-1-git-send-email-jhovold@gmail.com>
Use gpio_is_valid rather than open coding the more restrictive != -1
test.
