Subject: [PATCH] HSI: omap_ssi_core: fix possible memory leak in ssi_probe()
Git-commit: 1aff514e1d2bd47854dbbdf867970b9d463d4c57
Patch-mainline: v6.2-rc1
References: git-fixes
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")
