Currently drm_bridge_connector_init() reuses the 'bridge' variable, first
as a loop variable in the long drm_for_each_bridge_in_chain() and then in
the HDMI-specific code as a shortcut to bridge_connector->bridge_cec.
We are about to remove the 'bridge' loop variable for
drm_for_each_bridge_in_chain() by moving to a scoped version of the same
macro, which implies removing the 'bridge' variable from the main function
scope. Additionally reusing the variable can make such long function less
readable.
Similarly to what commit 6f727c838ea8 ("drm/bridge-connector: Fix bridge in
drm_connector_hdmi_audio_init()") already did for the audio HDMI bridge,
use n local variable inside the scopes where it is needed as a
bridge_connector->bridge_hdmi_cec shortcut to make its scope clearer as
well as to allow removing the 'bridge' variable in an upcoming commit.

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.
