Sudeep Holla 244f5d597e firmware: arm_ffa: Add missing remove callback to ffa_bus_type ... Currently the arm_ffa firmware driver can be built as module and hence all the users of FFA driver. If any driver on the ffa bus is removed or unregistered, the remove callback on all the device bound to the driver being removed should be callback. For that to happen, we must register a remove callback on the ffa_bus which is currently missing. This results in the probe getting called again without the previous remove callback on a device which may result in kernel crash. Fix the issue by registering the remove callback on the FFA bus.
