I couldn't find a patch adding this hunk in my e-mail archive so I'm
commenting here. Shouldn't V4L2_CID_USER_MEYE_BASE start at a higher value,
e.g. (V4L2_CID_USER_BASE + 0x1010) to account for drivers that already
use private controls ? There is couple of them with a few control IDs
starting at V4L2_CID_USER_BASE.
