1. Fix line over 80 characters warning.
2. The checkpatch warning at line 499 seems to be false positive.

The else condition here cannot be eliminated
You can try something like this to eliminate the else:

        list_add_tail(&(prframe->u.hdr.list), plist);

NACK on this idea. Checkpatch is not the complete arbiter of style. Just leave 
the code alone.
