Subject: [PATCH] Input: gpio_keys_polled - convert to devm-* API

Replace existing resource handling in the driver with managed device
resources, this ensures more consistent error values and simplifies error
handling paths:

kzalloc -> devm_kzalloc
gpio_request_one -> devm_gpio_request_one
input_allocate_polled_device -> devm_input_allocate_polled_device
