Ondrej Jirman 8ed8528346 media: sun6i-csi: Allow the video device to be open multiple times
Previously it was possible, but a recent fix for uninitialized
`ret` variable broke this behavior.

v4l2_fh_is_singular_file() check is there just to determine
whether the power needs to be enabled, and it's not a failure
if it returns false.

Fixes: ba9139116bc0 ("media: sun6i-csi: add a missing return code")

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.
