[PATCH] drm/bridge: ti-sn65dsi86: Put the host node if DSI attachment fails

[Wentao Liang]

ti_sn_bridge_parse_dsi_host() takes a reference to the remote DSI host
node. If ti_sn_attach_host() fails, ti_sn_bridge_probe() removes the
bridge but leaves the node reference held. The remove callback is not
called after failed probe, so a deferred probe can leak another reference
on each attempt.

Drop the host node reference in the existing attachment failure path.

at probe")
