Hello Juergen,
I've started to work on checkpatch-like python script. I make it based on clang-format-diff.py and it works as pre-commit hook.

It seems like specific script for style checking is not needed. Because clang-format tool does style checking by itself.
All we need is just to provide appropriate coding style description file for each.
Clang-format is a bit specific tool, so we can not specify
explicitly file with coding style description.
It just looks for a .clang-format file in one of a
parent directories of a file being checked.
As we got at least three coding-styles we have to substitute needed file in sources top directory for each check.
It could be done by generating .clang-format file
dynamically depending on style/path from the STYLES file.
Another way could be using appropriate symlink on existing .clang-format file which is located somewhere in tools/clang-format/coding-style-file
like:
tools/clang-format/xen-style
tools/clang-format/linux-style
tools/clang-format/xl-style
