From f4e1f999617b0d968fcb9ff2e5a4e1171d8d5d9f Mon Sep 17 00:00:00 2001 From: Martin Schiller Date: Tue, 27 Jun 2023 09:57:53 +0200 Subject: [PATCH] kernel: net: phy: realtek: fix rtl822x_probe on unsupported devices Calling rtl822x_probe() on phy devices which uses the rtl822x_read_mmd() and rtl822x_write_mmd() functions makes no sense and the probe ends with an EOPNOTSUPP error.
