Bryan O'Donoghue 52764bd8aa greybus: timesync: Bugfix ping should not result in -EAGAIN ... gb_timesync_schedule_synchronous() is currently making a synchronous FrameTime synchronization happen. It does a wait_event_interruptible() and then goes to check the status of the state-machine. Occasionally the state indicates PING - which is a completely valid state and should result in a result code of 0 not -EAGAIN. This patch fixes by making __gb_timesync_get_status() return 0 instead of -EAGAIN for the PING state.
