Subject: [PATCH] [3.10 LTS gpio] squelch a compiler warning

drivers/gpio/gpiolib-of.c: In function 'of_gpiochip_find_and_xlate':
drivers/gpio/gpiolib-of.c:51:21: warning: assignment makes integer from
pointer without a cast [enabled by default]
   gg_data->out_gpio = ERR_PTR(ret);
                     ^
this was introduced in d1c3449160df60fac4abb56f0ba0a3784305e43e

the upstream kernel changed the type of out_gpio from int to struct gpio_desc *
as part of a larger refactoring that wasn't backported
