[PATCH] ASoC: bcm: add missing call to of_node_put()

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

 



In one of the error paths of the for_each_child_of_node() loop,
add missing call to of_node_put().

Fix the following coccicheck warning:
./sound/soc/bcm/cygnus-ssp.c:1346:1-33: WARNING: Function
"for_each_available_child_of_node" should have of_node_put() before
return around line 1352.
