This is a note to let you know that I have just added a patch titled pinctrl: bcm2835: Fix memory leak in error path to the linux-4.2.y-queue branch of the 4.2.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-4.2.y-queue This patch is scheduled to be released in version 4.2.8-ckt3. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 4.2.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ---8<------------------------------------------------------------ From ff0860e67e5660c6812b5c4c094d8c50470ea8a6 Mon Sep 17 00:00:00 2001 From: Stefan Wahren <stefan.wahren@i2se.com> Date: Mon, 21 Dec 2015 00:44:04 +0000 Subject: pinctrl: bcm2835: Fix memory leak in error path commit 53653c6b91750debba6dc4503003c851257fd340 upstream. In case of an invalid pin value bcm2835_pctl_dt_node_to_map() would leak the pull configs of already assigned pins. So avoid this by calling the free map function in error case.
