6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Zimmermann <tzimmermann@xxxxxxx>
commit 5aed213c7c6c4f5dcb1a3ef146f493f18fe703dc upstream.
DisplayLink devices do not generate hotplug events. Remove the poll
flag DRM_CONNECTOR_POLL_HPD, as it may not be specified together with
DRM_CONNECTOR_POLL_CONNECT or DRM_CONNECTOR_POLL_DISCONNECT.
