Subject: Re: [PATCH] [STYLE]staging:skein:threefish_block.c remove blank lines

Hi Walt,

Thanks for the patch, unfortunately, it's a NAK.  If you search the ml
archives, you'll see this has been addressed before.

The double lines are deliberate to show a logical separation between the
blocks of code.  Ideally, the second blank line would be a comment
describing the following block.  However, I'm not smart enough yet to
add correct comments.  So, the blank lines remain. :-/

thx,
