I do. Here, I use:

$ make ARCH=i386 CF=-D__CHECK_ENDIAN__ CONFIG_DEBUG_SECTION_MISMATCH=y C=1 W=1 CHECK='compile_checks' M=drivers/media

Where "compile_checks" is actually a small script that calls both
smatch and sparse:

#!/bin/bash
/devel/smatch/smatch -p=kernel $@
/devel/sparse/sparse $@

So, I'm not sure why we need something else. That said, I didn't look
on its code, but looking on its diffstat:

Makefile | 23 +-
scripts/Makefile.build | 4 +-
scripts/runchecks | 734 ++++++++++++++++++++++++++-
scripts/runchecks.cfg | 63 ++-
scripts/runchecks_help.txt | 43 ++-

Using a 734 lines python program just to do an exec on an external checker
seems too much!

Thanks,
Mauro
