Ugh... I'd say this is one case where checkpatch.pl really shouldn't be
complaining since this isn't a function call or declaration. It's more
like a code snippet written with macros, so I don't think the same rules
should apply.

Adding checkpatch folks (hence quoting in full): is there anything we
can do about this without too much effort? Or should we just accept this
the way it is?

Re: [PATCH] staging: media: tegra-vde: Align line break to match with the open parenthesis in file trace.h

Hi Aline,

These trace headers are almost a language by themselves, and the
usual alignment rules do not apply. Look at other existing trace.h files
in the kernel and you'll see that they have their own coding style.

So I prefer not to apply this patch.

You couldn't have known that, so it's not your fault.

Regards,

	Hans

While it may be possible to add exceptions for trace headers on the
alignment rules, I don't know how many more such exceptions we will
end up adding. Such fine grained checks might be unnecessarily complex.
