[PATCH 4.4 080/135] net: sched: export __netdev_watchdog_up()

[Sasha Levin]

From: Valentin Longchamp <valentin@xxxxxxxxxxxx>

[ 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.

Fixes: 79dde73cf9bc ("net/ethernet/freescale: rework quiesce/activate for ucc_geth")
