From 3ffa9f713c39a213a08d9ff13ab983a8aa5d8b5d Mon Sep 17 00:00:00 2001 From: Yuan Can Date: Thu, 24 Nov 2022 11:33:32 +0000 Subject: [PATCH] HSI: omap_ssi_core: Fix error handling in ssi_init() 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.
