[ Upstream commit 1aff514e1d2bd47854dbbdf867970b9d463d4c57 ]
If ssi_add_controller() returns error, it should call hsi_put_controller()
to give up the reference that was set in hsi_alloc_controller(), so that
it can call hsi_controller_release() to free controller and ports that
allocated in hsi_alloc_controller().
Fixes: b209e047bc74 ("HSI: Introduce OMAP SSI driver")
