unlikely.

All the changes here are whitespace and comments, no code
or definitions changed. Not all issues were addressed, but
it is much better than it was. Mostly fixed was a lot
of "Excess union member" and ''rsvd' not described' warnings.
Fixes: c4e7a75a096c ("ionic: updates to ionic FW api description")
