From: Vaibhav Hiremath <[email protected]> Since access to TWL GPIO's can go into sleep, and using normal gpio_get/set_value() API will lead to kernel dump (of WARN_ON()).
On OMAP3EVM LCD backlight & DVI encoder is controller through TWL GPIO, so replacing normal gpio_get/set_value() to gpio_get_set_value_cansleep().
