You could run the coccinelle spatch file for bool
comparisons on the files instead.  It's much less
error prone.

$ spatch --sp-file scripts/coccinelle/misc/boolconv.cocci --in-place 
drivers/staging/rtl8723bs/

Or you could use a patch to checkpatch like below and then use

$ git ls-files drivers/staging/rtl8723bs | \
  xargs ./scripts/checkpatch.pl -f --fix-inplace --types=bool_comparison

but that definitely would not be as good as the coccinelle
tool use as coccinelle is much better at parsing expressions.
