+Subject: net: sched: export __netdev_watchdog_up()
+
+From: Valentin Longchamp <valentin@longchamp.me>
+
+[ Upstream commit 1a3db27ad9a72d033235b9673653962c02e3486e ]
+
+Since the quiesce/activate rework, __netdev_watchdog_up() is directly
+called in the ucc_geth driver.
+
+Unfortunately, this function is not available for modules and thus
+ucc_geth cannot be built as a module anymore. Fix it by exporting
+__netdev_watchdog_up().
+
+Since the commit introducing the regression was backported to stable
+branches, this one should ideally be as well.
