So think breaks more drivers:

https://lore.kernel.org/all/aYkdKfP5fg6iywgr@jekhomev/

I think it may also break:

arch/arm/mach-omap1/board-nokia770.c
arch/arm/mach-pxa/devices.c
arch/arm/mach-pxa/devices.h
arch/arm/mach-pxa/gumstix.c
arch/arm/mach-pxa/pxa25x.c
arch/arm/mach-pxa/pxa27x.c
arch/arm/mach-pxa/spitz.c
arch/arm/mach-tegra/board-paz00.c
arch/x86/platform/geode/geode-common.c
drivers/platform/x86/barco-p50-gpio.c
drivers/platform/x86/pcengines-apuv2.c

Thanks.
