[PATCH] drm/bridge: lt9611: Put DSI nodes if device tree parsing fails

[Wentao Liang <vulab@iscas.ac.cn>]

lt9611_parse_dt() obtains references to the remote DSI nodes before
looking up the downstream bridge. If that lookup fails, for example
with -EPROBE_DEFER, lt9611_probe() returns without releasing the DSI
node references.

Use the existing err_of_put cleanup path when parsing fails. Both node
pointers are zero-initialized, so this also handles a missing DSI node.
