This is a note to let you know that I have just added a patch titled backlight: atmel-pwm-bl: fix gpio polarity in remove to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 9bd32697ffaeff30c8c3da94f63a04793a6e4ace Mon Sep 17 00:00:00 2001 From: Johan Hovold <jhovold@gmail.com> Date: Tue, 12 Nov 2013 15:09:39 -0800 Subject: backlight: atmel-pwm-bl: fix gpio polarity in remove commit ad5066d4c2b1d696749f8d7816357c23b648c4d3 upstream. Make sure to honour gpio polarity also at remove so that the backlight is actually disabled on boards with active-low enable pin.
