Subject: [PATCH] checkpatch: fix spurious vendor compatible warnings
With a compatible string like
compatible = "foo";
checkpatch will currently try to find "foo" in vendor-prefixes.txt,
which is wrong since the vendor prefix is empty in this specific case.
Skip the vendor test if the compatible is not like
compatible = "vendor,something";
