From 4c5681acd75d0449ab5b6054142da93559598e39 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sat, 25 Mar 2023 22:56:09 +0200 Subject: [PATCH] media: i2c: adv7604: Enable video adjustment The video adjustments (contrast, brightness, saturation and hue) are ignored by default by the device when the VID_ADJ_EN bit is clear. The corresponding V4L2 controls exposed by the drivers have thus no effect. Fix this by setting the VID_ADJ_EN bit.
