Hey, they're original to the file.  I'm just keeping checkpatch.pl happy here.
Ditto for everything else you commented on.

Dig out your text editor, and notice the excess whitespace at the end of the line,
along with similar stuff on most other lines in this patch.
This is all just stuff that checkpatch.pl complains about when
the later patches are applied, so patch 01_... serves to reduce
the noise level from checkpatch.pl for the *real* patches which follow.
