Hi Linus, Here's a set of (rather RFC) patches, to implement pinctrl_gpio_get_direction(). I did that, because my gpio-ingenic driver calls pinctrl_gpio_set_direction() within its gpio_chip's .set_direction callback, but there was no corresponding function to implement the .get_direction callback. If that's not the right way to do it, please advise.
If not merging the whole series, patch [3/5] is a real fix that should go through. Note that it doesn't make checkpatch.pl happy, I wasn't sure whether I should try to comply to checkpatch.pl or match the coding style in the pinctrl subsystem, I chose the latter. Thanks, -Paul
