This series adds support for dynamic array controls and for a new v4l2_ctrl_modify_dimensions() function to modify the dimensions of an array control by the driver. The dynamic array patches are unchanged and are already used in two patch series (stateless HEVC uAPI and the dw100 driver), but they are added here since the last 5 patches that add support for v4l2_ctrl_modify_dimensions() build on those. The vivid driver is also extended with such controls to make it possible to test this. Xavier, the v4l2_ctrl_modify_dimensions() are mostly identical to the patches I mailed you before and that you added to v6 of dw100. Just improved documentation and commit logs and a minor checkpatch fix. For a v7 of your driver, please use this series.
