This means that the driver is trying to register with the same name as
another driver on the same bus.

Nice to see we at least recover from it and don't kill the kernel :)

It has been duplicated and made change in megaraid legacy driver.
The module name for the driver will be 'megaraid_legacy' from 'megaraid'.
Patch will be followed soon.

Thank you,
