Luca Ceresoli b402753693 Revert "drm/display: bridge_connector: get/put the stored bridges" 
This reverts commit 2be300f9a0.

The commit being reverted moved all the bridge_connector->bridge_*
assignments to just before the final successful return in order to handle
the bridge refcounting in a clean way.

This introduced a bug, because a bit before the successful return
drmm_connector_hdmi_cec_register() is called, which calls funcs->init()
which is drm_bridge_connector_hdmi_cec_init() which needs
bridge_connector->bridge_hdmi_cec to be set.

The reported bug may be fixed in a relatively simple way, but other similar
patterns are potentially present, so just revert the offending commit. A
different approach will be implemented.

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 reStructuredText 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.
