Subject: [PATCH v2] drm: xlnx: zynqmp_dpsub: fix hotplug detection
From: Steffen Dirkwinkel <s.dirkwinkel@...khoff.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")
