Regression: DVBSky S960 USB tuner doesn't work in 4.10 or newer

Hello Peter and Max, I noticed that when using kernel 4.10 or newer my DVBSky S960 and S960CI satellite USB TV tuners stopped working properly. Basically, they will fail at one point when tuning to a channel. This typically takes less than 100 tuning attempts. For perspective, when performing a

[PATCH v8 2/2] v4l: cadence: Add Cadence MIPI-CSI2 TX driver

The Cadence MIPI-CSI2 TX controller is an hardware block meant to be used as a bridge between pixel interfaces and a CSI-2 bus. It supports operating with an internal or external D-PHY, with up to 4 lanes, or without any D-PHY. The current code only supports the latter case. While the virtual
