Hello,
I've just noticed that there is a problem with this patch on
kgene/for-next branch. It causes compilation break:
arch/arm/mach-exynos4/cpu.c:106: error: 'S5P_VA_AUDSS' undeclared here (not in a
function)
make[1]: *** [arch/arm/mach-exynos4/cpu.o] Error 1
make: *** [arch/arm/mach-exynos4] Error 2
make: *** Waiting for unfinished jobs....
It looks that some definitions are still missing there.
