   4 Subject: [PATCH] phy-core: Don't propagate -ENOSUPP from
   5  phy_pm_runtime_get_sync to caller
   6
   7 The phy-core allows phy_init and phy_power_on to be called multiple times,
   8 but before this patch -ENOSUPP from phy_pm_runtime_get_sync would be
   9 propagated to the caller for the 2nd and later calls.
