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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
