This reformats the GUID definitions in include/linux/efi.h so that if
you add another one with the same style, checkpatch won't complain about
it.

So I really think this is a step backwards.

Checkpatch should be fixed/enhanced to allow targeted exemption. Something like:


	#define CHECKPATCH_IGNORE
	...
	#undef CHECKPATCH_IGNORE

... which checkpatch would parse and interpret accordingly.

Irrespective of which tool suggested this change, I think this patch
is an improvement because the GUIDs now match the format from the UEFI
spec, making checking for typos that much easier (yes, I've really had
to do that in the past).

Hm, so the GUIDs are line-broken in the same fashion in the spec, after the third 
parameter?

That's a strong reason indeed - and then the changelog and title should say that: 
're-format GUID tables to follow the format of the UEFI spec'. That it also 
pacifies checkpatch is a side effect.

Thanks,
