commit107927fa59upstream. In imx_media_create_csi_of_links(), the 'struct v4l2_fwnode_link' must be cleared for each endpoint iteration, otherwise if the remote port has no "reg" property, link.remote_port will not be reset to zero. This was discovered on the i.MX53 SMD board, since the OV5642 connects directly to ipu1_csi0 and has a single source port with no "reg" property.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
