Please enable CONFIG_VIDEO_EM28XX_V4L2=m

Hi,
Please enable CONFIG_VIDEO_EM28XX_V4L2=m.
I believe that this is required to enable V4L2 to work correctly with EM28XX devices since version 0.2.1 of the driver

thanks,

Fergal

This should be in now - can you rpi-update and test?

Thanks,

The device is now appearing as video0 in /dev and responds to v4l2-ctl

pi@pi2 ~ $ v4l2-ctl --all

I'll test how it behaves later, but at least it is accessible now.

thanks again for enabling it.
