[PATCH 6.12 736/826] soc: fsl: rcpm: fix missing of_node_put() in copy_ippdexpcr1_setting()

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

 



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

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

From: Javier Carrasco <javier.carrasco.cruz@xxxxxxxxx>

commit c9f1efabf8e3b3ff886a42669f7093789dbeca94 upstream.

of_find_compatible_node() requires a call to of_node_put() when the
pointer to the node is not required anymore to decrement its refcount
and avoid leaking memory.

Add the missing call to of_node_put() after the node has been used.
