                    module does not return device busy first time

11.2-RELEASE-p4

Steps-
1. I have a kernel moduleA that is dependent on other kernel moduleB and if=
 I
try to unload moduleA, it returns no error=20
2. And if I repeat step 1 it returns device busy error message.
3. Now unload moduleB and it removed successfully
4. Now by default module A is unloaded without giving user any clue.
