Hi all,
After merging the irqchip tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:
In file included from include/linux/io.h:25,
from include/linux/of_address.h:7,
from drivers/irqchip/irq-imx-gpcv2.c:9:

Introduced by commit
ed01edc0ab6f ("irqchip/irq-imx-gpcv2: Add support for i.MX8MQ")
This is caused by my use of -Wimplicit-fallthrough for Kees Cook.
Replacing the "/* FALLTHROUGH */" with "/* fall through */" but on the
line above will suppress the warning.
