Subject: [PATCH 01/10] ARM: S3C24XX: Free the backlight gpio requested in Mini2440 board code
Date: Sat, 30 Jun 2012 14:08:53 +0200	[thread overview]
Message-ID: <1341058142-30438-2-git-send-email-sylvester.nawrocki@gmail.com> (raw)
In-Reply-To: <1341058142-30438-1-git-send-email-sylvester.nawrocki@gmail.com>

The backlight gpio must not be left requested in the board
code, otherwise s3c24xx_led driver can't successfully claim it.
So request the backlight gpio, configure it to proper state and
gpio_free right away.

This change is required for converting the s3c24xx_led driver
to the gpiolib API.
