Andy Shevchenko ba10157cd0 media: ipu3-cio2: Fix reference counting when looping over ACPI devices 
[ Upstream commit 2cb2705cf7 ]

When we continue, due to device is disabled, loop we have to drop
reference count. When we have an array full of devices we have to also
drop the reference count. Note, in this case the
cio2_bridge_unregister_sensors() is called by the caller.

Fixes: 803abec64e ("media: ipu3-cio2: Add cio2-bridge to ipu3-cio2 driver")

README 

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.
