This error appeared in the bcmring_defconfig build:
CC arch/arm/mach-bcmring/core.o
arch/arm/mach-bcmring/core.c:55: error: macro "AMBA_APB_DEVICE" requires 6 arguments, but only 5 given
arch/arm/mach-bcmring/core.c:55: warning: type defaults to 'int' in declaration of 'AMBA_APB_DEVICE'

arch/arm/mach-bcmring/core.c:135: error: 'uartB_device' undeclared here (not in a function)
make[2]: *** [arch/arm/mach-bcmring/core.o] Error 1
It appeared as of commit 8ede1ae65e
"ARM: amba: bcmring: use common amba device initializers"
Note that in include/linux/amba/bus.h we have:
#define AMBA_APB_DEVICE(name, busid, id, base, irqs, data) ...
There is an a --> A case error in the busid and a missing zero
placeholder for the id field.
