The rockchip IQ tool sends data via usb uvc. The data buf
of v4l2_event is used for IQ tool userspace on uvc device
side to receive vendor specific data from host, the max
length of data maybe 4096 bytes, so increase the data length
of v4l2_event to 4100.
I have already tested the usb host uvc function, it works
well with this patch.
Note:
The userspace need to update the data length of v4l2_event
to 4100 synchronously.
