I actually deliberately grouped it with mmc_gpiod_request_cd() since
it operates on the gpiod requested by that / since this is sorta an
alternative to just adding a config param to mmc_gpiod_request_cd()
mirroring the existing debounce parameter.

With that said I've no objections against moving it either. So whatever
you prefer.

Regards,

Hans
