Return values

Hi dudes,

Is it better to test the return values of
	1) register_chrdev with -EBUSY
	2) unregister_chrdev with -EINVAL
instead of doing if(ret_val < 0)?

I looked at the code in fs/devices.c, and noticed
that the return values if an error occurs is -EBUSY
for register_chrdev, and -EINVAL for unregister_chrdev.
