[PATCH 0/5] pinctrl_gpio_get_direction & ingenic fixes

[Paul Cercueil <paul@xxxxxxxxxxxxxxx>]

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
