On arm32 allyesconfig:

drivers/pinctrl/pinctrl-artpec6.c:706:13: error: unused function
'artpec6_pmx_disable' [-Werror,-Wunused-function]

This is the second time you've introduced an unused function warning by
making a function static[1], could you please be a little more vigilant
in your clean ups in the future?

Linus/Jesper/Lars, should this function just be deleted? I'd be happy to
send a patch doing so if that's the right course of action.

Thanks,
Nathan
