Sure, no probs.
Btw, if you really want to try to fix some bugs, you could try to build
the kernel with
make -j<number-of-cores-on-your-machine> W=n 2>build-warnings.log
where n is 1, 2 or 3 (or any subset of those) and try to analyze them.
Look at the output in build-warnings.log and try to understand why the
compiler is complaining and whether it makes sense.
Some of them might be worth fixing. Most of them are bogus and/or fixing
them would require just too much code changes for no real gain but some
of the warnings do make sense.
Also, you could do
before that so that you can build *everything* and catch all warnings.
