Cover letter [PATCH 0/5] gpio: Utilize devm_ functions in driver probe callbacks
The devm_ resource manager functions allow memory to be automatically released when a device is unbound. This patchset takes advantage of the resource manager functions and replaces gpiochip_add_data calls and request_irq calls with devm_gpiochip_add_data calls and devm_request_irq calls respectively.
A convenient outcome of these changes is the removal of the respective driver remove callback functions for these drivers; now that clean-up is handled automatically when devices are unbound, custom driver remove functions are no longer necessary for these drivers.
