I understand the patch and why it's correct. I just wondered why it
works correctly without this patch.

ls arch/arm/cpu/../../../../lib/decompress_inflate.c
ls: cannot access arch/arm/cpu/../../../../lib/decompress_inflate.c: No such file or directory

This is correct, we only have to go three directories up. Still it
compiles fine.
