PATCH 1/1 gspca - ov534: Fix the light frequency filter.
From: Jean-François Moine <[email protected]>
The exchanges relative to the light frequency filter were adapted from a description found in a ms-windows driver. It seems that the registers were the ones of some other sensor.
This patch was done thanks to the documentation of the right OmniVision sensors.
Note: The light frequency filter is either off or automatic. The application will see either off or "50Hz" only.
