This is a note to let you know that I've just added the patch titled MIPS: Remove repetitive increase irq_err_count to the 5.15-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: mips-remove-repetitive-increase-irq_err_count.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 0a752cdee9b3ef018894db578a76f890db854f5e Author: huhai <huhai@xxxxxxxxxx> Date: Fri Jun 10 19:14:20 2022 +0800 MIPS: Remove repetitive increase irq_err_count [ Upstream commit c81aba8fde2aee4f5778ebab3a1d51bd2ef48e4c ] commit 979934da9e7a ("[PATCH] mips: update IRQ handling for vr41xx") added a function irq_dispatch, and it'll increase irq_err_count when the get_irq callback returns a negative value, but increase irq_err_count in get_irq was not removed. And also, modpost complains once gpio-vr41xx drivers become modules. ERROR: modpost: "irq_err_count" [drivers/gpio/gpio-vr41xx.ko] undefined! So it would be a good idea to remove repetitive increase irq_err_count in get_irq callback.
