Hans de Goede 5de39b2b1f V4L/DVB (8374): gspca: No conflict of 0c45:6011 with the sn9c102 driver. 
The sn9c102 driver claims to support usb-ID 0x0c45:0x6011, which is
a sn9c102 with ov6650 sensor, but the sn9c102 driver does not support the
ov6650 sensor (tested). Also the sn9c102 driver claims to support usb-ID
0x0c45:0x603f, which is a sn9c102 with CISVF10 sensor, but the sn9c102
driver does not support the CISVF10 sensor (not tested).
