Peng, if you are still interested in continuing this task, you can focus on
converting the drivers that use gpio_request_one() and devm_gpio_request_one().
These are some like a couple of dozens only (in comparison to the gpio_request()
and devm_gpio_request() users). Some of them are resided in the ASoC subsystem.
