[ Upstream commit 00512d2930b338fdd42bd90bbd1793fe212c2d31 ]
The ffa core driver currently assigns its own driver information to individual ffa device driver_data which is wrong. Firstly, it leaks this core driver information to individual ffa_device and hence to ffa_driver. Secondly the ffa_device driver_data is for use by individual ffa_driver and not for this core driver managing all those devices.
