Hello, This patch series adds support for the Cubic Look Up table (CLU) to the vsp1 driver. The first three patches are small unrelated fixes, I've included them here to get them review and they will be added to the next pull request for the vsp1 driver. Patch 4/5 replaces the custom ioctl used to configure the 1D lookup table (LUT) by an array control, to align it with the CLU API. This isn't an issue as there's no user of this API with the mainline kernel. Finally patch 5/5 adds support for the CLU, exposing the look-up table contents through a control. The look-up table being quite large, I will likely work on supporting partial control updates in the control framework at some point. Feel free to beat me to it.
