Subject: [PATCH 6/8] phy-core: Don't propagate -ENOSUPP from phy_pm_runtime_get_sync to caller

From: Hans de Goede <hdegoede@...hat.com>

The phy-core allows phy_init and phy_power_on to be called multiple times,
but before this patch -ENOSUPP from phy_pm_runtime_get_sync would be
propagated to the caller for the 2nd and later calls.
