Hi Linus,

Sorry for the trouble. Three patches were sent by mistake. I am rebasing this patch on top of your gpio fixes branch.
This might not be required for stable branch since the original patch
4c806c9 "gpio: mxc: add generic gpio request/free callbacks to pinctrl" was included in v4.9 so this cane be added in
v4.9 fixes.

with warm regards,
Deepak Das
