[PATCH 5.10 156/529] gpu: ipu-v3: common: Add of_node_put() for reference returned by of_graph_get_port_by_id()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Liang He <windhl@xxxxxxx>

[ Upstream commit 9afdf98cfdfa2ba8ec068cf08c5fcdc1ed8daf3f ]

In ipu_add_client_devices(), we need to call of_node_put() for
reference returned by of_graph_get_port_by_id() in fail path.

Fixes: 17e052175039 ("gpu: ipu-v3: Do not bail out on missing optional port nodes")
