We have a bad habit of calling drm_fb_helper_hotplug_event() far more then we actually need to. MST appears to be one of these cases, where we call drm_fb_helper_hotplug_event() if we fail to resume a connected MST topology in intel_dp_mst_resume(). We don't actually need to do this at all though since hotplug events are already sent from drm_dp_connector_destroy_work() every time connectors are unregistered from userspace's PoV. Additionally, extra calls to drm_fb_helper_hotplug_event() also just mean more of a chance of doing a connector probe somewhere we shouldn't. So, don't send any hotplug events during resume if the MST topology fails to come up. Just rely on the DP MST helpers to send them for us.

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.
