No other V4L2 driver resets the selected input (front cam or back cam selected in case of the atomisp). Stop resetting selected input to 0 between /dev/video# opens. This allows e.g. using v4l2-ctl -i to switch the input before starting another app, which is useful since most apps don't support selecting the input. Note more in general the whole resetting of a bunch of internal state from the open fop needs to be removed there to allow multiple opens of /dev/video# for full v4l2 API compliance.
