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.
