All other functions that manipulate a struct gpio_desc use the gpiod_
prefix. Follow this convention and rename gpio_set_debounce_timeout() to
gpiod_set_debounce_timeout().

All the other ones are static to gpiolib.c. With static symbols the
naming convention is a bit more relaxed throughout the kernel. But I
do agree and I will get to them in time. :)

Even if I agreed with your other comment, gpio_chip_hwgpio() is a
terrible name and if I didn't know, I couldn't tell you what it does
just from looking at the name.

Probably my fault.

"For the chip containing this desc obtain the corresponding
hardware GPIO number/offset" is what I would put in kerneldoc.
(Which is by the way also horrible.)

Let's rename it to something that says clearly what it does.
(Rusty Russell's API design hierarchy.)

I guess I would just name it something like *_get_chip_hw_offset()
or *_get_chip_hwgpio_offset() but it gets a bit long, maybe it is a bit
talkative but easy to understand. (I stay off the prefix discussion.)

Yours,
Linus Walleij
