Subject[PATCH 0/5] gpio: Utilize devm_ functions in driver probe callbacks
Date
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.
