What I meant to say was I don't care as much about mixing
multiple types of fixes in a single patch as others might.

Greg does and generally rejects patches that mix fix types.

My preference is to do _all_ whitespace changes in a single
patch.  If "git diff -w" shows no source code changes, and
objdiff shows no object code change, that's a "single type"
of change to me.

Others disagree and may want whitespace changes broken down
into finer-grained blocks.

I think it's not necessary to modify the same line multiple
times just to get this granularity.

btw: using:

$ ./scripts/checkpatch.pl -f --strict --fix-inplace \
   --types=spacing,space_before_tab,pointer_location,trailing_whitespace,bracket_space,space_before_tab,indented_label,parenthesis_alignment \
   $file

can do this moderately well and there's a trivial script to
use checkpatch and git to create a patch series for various
checkpatch type style messages.
