The devm_ resource manager functions allow memory to be automatically released when a device is unbound. This patch takes advantage of the resource manager functions and replaces the gpiochip_add_data call with the devm_gpiochip_add_data call. In addition, the gpiomm_remove function has been removed as no longer necessary due to the use of the relevant devm_ resource manager functions.
