zhangzhijie a9fc431555 drm: Improve the output_poll_changed description
this callback was used by drm_kms_helper_hotplug_event()

V2: (Thanks for Daniel's suggestions)
- remove the FIXME below.since with the drm_client
- infrastructure and the generic fbdev emulation we've
- resolved this all very neatly now.

V3: Add comments that This hook is deprecated
- new implementation methods instead of this hook

v4: used by drm_kms_helper_hotplug_event()
- drm_fb_helper_hotplug_changed() is not found
instead by drm_kms_helper_hotplug_event()

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.
