Yes, most style issues are in files copied from the kernel side, before
sending v2, I do have a brief look and fix some of them (for example,
mixed TAB/space and multiple empty lines).

But the diff quoted here isn't copied from kernel side, it's written by
myself. I consider the double space meaningful since these two macros
are two possible values of CACHE_OP, and found similar styles in
tools/zynqmqimage.h (PART_ATTR_*) and kernel side, do you think it's
acceptable?
