From ea8318cb33e593bbfc59d637eae45a69732c5387 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Wed, 15 Jan 2025 14:43:43 +0000 Subject: [PATCH] net: phy: realtek: clear master_slave_state if link is down rtlgen_decode_physr() which sets master_slave_state isn't called in case the link is down and other than rtlgen_read_status(), rtl822x_c45_read_status() doesn't implicitely clear master_slave_state. Avoid stale master_slave_state by always setting it to MASTER_SLAVE_STATE_UNKNOWN in rtl822x_c45_read_status() in case the link is down.
