And request_threaded_irq() Not to forget that it would/will be a big problem, if you will forbid drivers to use gpio_request() when they use the gpio as irq (as it was/is necessary now). With my kernel 3.10.4 with some patches on top, I see # git grep gpio_to_irq | wc -l 678 So there are a lot of places where gpio_request(); gpio_direction_input() request_irq(); would have been changed to #ifdef CONFIG_OF_GPIO gpio_request(); gpio_direction_input() #endif request_irq(); to not fail during runtime (hopefully with some descriptive error message if it fails).
