Hauke already fixed a couple of them, but one instance remains that checks for a negative integer when it should check for a NULL pointer:
arch/mips/lantiq/xway/sysctrl.c: In function 'ltq_soc_init': arch/mips/lantiq/xway/sysctrl.c:473:19: error: ordered comparison of pointer with integer zero [-Werror=extra]
