This is a note to let you know that I've just added the patch titled ARM: imx5: add missing put_device() call in imx_suspend_alloc_ocram() to the 4.19-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: arm-imx5-add-missing-put_device-call-in-imx_suspend_.patch and it can be found in the queue-4.19 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit d28e6b927679b6116a7cc5de9fcc0741a840a625 Author: yu kuai <yukuai3@xxxxxxxxxx> Date: Thu Jun 4 20:42:06 2020 +0800 ARM: imx5: add missing put_device() call in imx_suspend_alloc_ocram() [ Upstream commit 586745f1598ccf71b0a5a6df2222dee0a865954e ] if of_find_device_by_node() succeed, imx_suspend_alloc_ocram() doesn't have a corresponding put_device(). Thus add a jump target to fix the exception handling for this function implementation. Fixes: 1579c7b9fe01 ("ARM: imx53: Set DDR pins to high impedance when in suspend to RAM.")
