[ Upstream commit 98ea51cb0c8ce009d9da1fd7b48f0ff1d7a9bbb0 ]
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]
Fixes: 6e807852676a ("MIPS: Lantiq: Fix check for return value of request_mem_region()")
