Hmm, too late it seems...
Patch should actually remove <linux/gpio.h> as this is legacy one (see comment
on the top and also Documentation/driver-api/gpio/consumer.rst)

And that brings a question. Given this is -next only is it actually possible
to squash fixes into 1a476abc723e ("tas2770: add tas2770 smart PA kernel driver")
just to make bisect a bit more happy?
