I don't think you can guarantee the "gpio --> mmc" sequence if both
drivers use module_init (the order could be completely random, generally
it depends on what Kbuild is doing), but if gpio_request() behaves as
Linus said, the sequence in the problematic scenario would be "pinctrl
--> mmc --> EPROBE_DEFER --> gpio --> mmc" which is fine (subject to
mmci driver fix, but it's a separate issue).
Pawe?
