Silence the driver warnings, if we see "-w" on the Driver. Summary: We can enable warnings after that -w, so the patch might not be 100% correct. The problem that triggered this is: we have some amount of tests that expect 0 warnings (including unit tests for -w), but -w ends up not fully silencing everything.
