I was aware of the kfree(NULL) thing, but desided to leave it as is for two reasons - 1) kfree(NULL) is harmless and this is an error path, so the extra function call doesn't matter much. 2) I wanted to preserve deallocations in the reverse order of the allocations. But sure, moving that kfree is a tiny optimization of the error path, so I'm fine with it.
