This patch makes the HVR-950q behave consistently with other drivers, which is to show the signal level as 100% in cases where we have a signal present but given we are unable to determine an actual signal level. The old code would set the value to "1", which divided by 65535 is rounded down to 0%.

au8522: set signal field to 100% when signal present From: Devin Heitmueller <[email protected]> The signal state field in G_TUNER is typically scaled from 0-100%. Since we don't know the signal level, we really would prefer the field to contain 100% than 1/256, which in many utilities (such as v4l2-ctl) rounds to 0% even when a signal is actually present. This patch makes the behavior consistent with other drivers.
