[PATCH v2] drm: xlnx: zynqmp_dpsub: fix hotplug detection

Posted by Steffen Dirkwinkel 3 weeks, 6 days ago

From: Steffen Dirkwinkel <s.dirkwinkel@beckhoff.com>

drm_kms_helper_poll_init needs to be called after zynqmp_dpsub_kms_init.
zynqmp_dpsub_kms_init creates the connector and without it we don't
enable hotplug detection.

Fixes: eb2d64bfcc17 ("drm: xlnx: zynqmp_dpsub: Report HPD through the bridge")
