Hans de Goede ef0feca22e media: atomisp: Stop resetting selected input to 0 between /dev/video# opens
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.
