On several HP models (tested on HP 3125 and HP Probook 455 G2),
spurious unplug events are emitted upon login on Chrome OS.
This is likely due to the way Chrome OS restarts graphics
upon login, so it's possible it's an issue on other
distributions but not as common, though I haven't
reproduced the issue elsewhere.
Use logic from an earlier version of the merged change
(see link below) which iterates over connectors and finds
matching encoders, rather than the other way around.
Also fixes an issue with screen mirroring on Chrome OS.
I've deployed this patch on Fedora and did not observe
any regression on these devices.

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.
