This is a note to let you know that I have just added a patch titled gpio: sysfs: fix memory leak in gpiod_export_link to the linux-3.13.y-queue branch of the 3.13.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.13.y-queue This patch is scheduled to be released in version 3.13.11-ckt17. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.13.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 0e77f2aeeade0ea980071b57cfdb59d96cd8e85a Mon Sep 17 00:00:00 2001 From: Johan Hovold <johan@kernel.org> Date: Mon, 26 Jan 2015 12:02:45 +0100 Subject: gpio: sysfs: fix memory leak in gpiod_export_link commit 0f303db08df0df9bd0966443ad6001e63960af16 upstream. Fix memory leak in the gpio sysfs interface due to failure to drop reference to device returned by class_find_device when creating a link.
