In this patch: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=16dc42e018c2868211b4928f20a957c0c216126c the check was added for another driver to already claim the same device on the same bus. But the returned error code was wrong: to modprobe, the -EEXIST means that _this_ driver is already installed. It therefore doesn't produce the needed error message when _another_ driver is trying to register for the same device. Returning -EBUSY fixes the problem.
