Imre Deak 72e6d66877 drm: Fix output poll work for drm_kms_helper_poll=n 
If drm_kms_helper_poll=n the output poll work will only get scheduled
from drm_helper_probe_single_connector_modes() to handle a delayed
hotplug event. Since polling is disabled the work in this case should
just call drm_kms_helper_hotplug_event() w/o detecting the state of
connectors and rescheduling the work.

After commit d33a54e399 after a delayed hotplug event above the
connectors did get re-detected in the poll work and the work got
re-scheduled periodically (since poll_running is also false if
drm_kms_helper_poll=n), in effect ignoring the drm_kms_helper_poll=n
kernel param.

Fix the above by calling only drm_kms_helper_hotplug_event() for a
delayed hotplug event if drm_kms_helper_hotplug_event=n, as was done
before d33a54e399.

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 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.
