From 830f5ce266ce79e18f0026c36c99319b1bc08e1b Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 29 May 2020 13:02:07 +0300 Subject: [PATCH] net: phy: marvell: unlock after phy_select_page() failure We need to call phy_restore_page() even if phy_select_page() fails. Otherwise we are holding the phy_lock_mdio_bus() lock. This requirement is documented at the start of the phy_select_page() function.
