From 1cfe51ef07ca3286581d612debfb0430eeccbb65 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET christophe.jaillet@wanadoo.fr Date: Tue, 13 May 2025 19:56:41 +0200 Subject: [PATCH] i2c: designware: Fix an error handling path in i2c_dw_pci_probe()
If navi_amd_register_client() fails, the previous i2c_dw_probe() call should be undone by a corresponding i2c_del_adapter() call, as already done in the remove function.
