Subject: [PATCH] ath11k: add missing of_node_put() to avoid leak
|
|
|
|
The node pointer is returned by of_find_node_by_type()
|
|
or of_parse_phandle() with refcount incremented. Calling
|
|
of_node_put() to aovid the refcount leak.
|
|
|
|
Fixes: 6ac04bdc5edb ("ath11k: Use reserved host DDR addresses from DT for PCI devices")
