Greg Kroah-Hartman 94c0308279 Revert "pinctrl: intel: Initialize GPIO properly when used through irqchip" 
This reverts commit f5a26acf01

Mike writes:
	It seems that commit f5a26acf01 ("pinctrl: intel: Initialize GPIO
	properly when used through irqchip") can cause problems on some Skylake
	systems with Sunrisepoint PCH-H. Namely on certain systems it may turn
	the backlight PWM pin from native mode to GPIO which makes the screen
	blank during boot.

	There is more information here:

	  https://bugzilla.redhat.com/show_bug.cgi?id=1543769

	The actual reason is that GPIO numbering used in BIOS is using "Windows"
	numbers meaning that they don't match the hardware 1:1 and because of
	this a wrong pin (backlight PWM) is picked and switched to GPIO mode.

	There is a proper fix for this but since it has quite many dependencies
	on commits that cannot be considered stable material, I suggest we
	revert commit f5a26acf01 from stable trees 4.9, 4.14 and 4.15 to
	prevent the backlight issue.
