6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 4ea3deda1341fef7b923ad9cfe5dd46b1b51bfa8 ]

If zynqmp_dpsub_drm_init() fails, we must undo the previous
drm_bridge_add() call.

Fixes: be3f3042391d ("drm: zynqmp_dpsub: Always register bridge")
