6.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe JAILLET christophe.jaillet@wanadoo.fr
commit 1cfe51ef07ca3286581d612debfb0430eeccbb65 upstream.
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.
