From 2634387bc49f75c0f1d61a02d859ba83a328a215 Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Thu, 21 Oct 2021 21:08:02 +0800 Subject: [PATCH] mfd: tqmx86: Clear GPIO IRQ resource when no IRQ is set stable inclusion from stable-5.10.68 commit 87479b10eb72f82aa45e8dc6a3dd9bfaec38f9d7 bugzilla: 182671 https://gitee.com/openeuler/kernel/issues/I4EWUH Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=87479b10eb72f82aa45e8dc6a3dd9bfaec38f9d7 -------------------------------- [ 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.
