BTW, I can tell you why you don't see this error - you're building with
DT enabled, which gives you this header path to those definitions:

arch/arm/mach-omap2/prm44xx.c
arch/arm/mach-omap2/common.h
plat/common.h
plat/i2c.h
linux/i2c.h
linux/of.h
asm/prom.h
asm/irq.h
mach/irqs.h
plat/irqs.h
plat/irqs-44xx.h

which, I think you'll agree, is a recipe for disaster if any one of those
decides not to include its child at some point either via configuration
or via mere deletion of an include.
