[ Upstream commit 3ffa9f713c39a213a08d9ff13ab983a8aa5d8b5d ]
The ssi_init() returns the platform_driver_register() directly without checking its return value, if platform_driver_register() failed, the ssi_pdriver is not unregistered. Fix by unregister ssi_pdriver when the last platform_driver_register() failed.
