This is a note to let you know that I've just added the patch titled mfd: tqmx86: Clear GPIO IRQ resource when no IRQ is set to the 5.4-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: mfd-tqmx86-clear-gpio-irq-resource-when-no-irq-is-se.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 5b26574c1fdf5fca7371a5108e8fa144b7a3d7af Author: Matthias Schiffer <matthias.schiffer@xxxxxxxxxxxxxxx> Date: Fri Jul 16 12:00:48 2021 +0200 mfd: tqmx86: Clear GPIO IRQ resource when no IRQ is set [ Upstream commit a946506c48f3bd09363c9d2b0a178e55733bcbb6 ] The driver was registering IRQ 0 when no IRQ was set. This leads to warnings with newer kernels. Clear the resource flags, so no resource is registered at all in this case.
