Hello, This small series fixes two issues with video adjustments (brightness, contrast, saturation and hue) in the adv7604 driver. Patch 1/2 makes those controls effective (they currently have no effect), and patch 2/2 fixes the range of the hue control. I have successfully tested the series with an ADV7612, and Hans with the ADV7604. The ADV7604 and ADV7611 documentation of the hue control differs from the ADV7612, but I believe that's because earlier documentation was incorrect. In patch 2/2 I've decided to represent the hue value as an unsigned 8-bit integer, mapping to the [0°, 360°[ range. Using a signed value would map to the [-180°, 180°[ range instead, without making any other difference (and without requiring any modification to the patch other than changing the range). I don't have a strong preference between the two options, and I'm pretty sure we can freely pick one without any fear of an impact on existing userspace applications as patch 1/2 shows that the hue control has currently no effect. Compared to v1, this version fixes a typo in the commit message of patch 2/2.
