Revert "s390/mem_detect: do not update output parameters on failure"
This reverts commit cbc29f107e
.
Get rid of the following smatch warnings:
arch/s390/include/asm/mem_detect.h:86 get_mem_detect_end() error: uninitialized symbol 'end'.
arch/s390/include/asm/mem_detect.h:86 get_mem_detect_end() error: uninitialized symbol 'end'.
arch/s390/boot/vmem.c:256 setup_vmem() error: uninitialized symbol 'start'.
arch/s390/boot/vmem.c:258 setup_vmem() error: uninitialized symbol 'end'.
Note that there is no bug in the code. This is purely to silence smatch.
