[PATCH] crypto/nx: 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:
./drivers/crypto/nx/nx-common-powernv.c:927:1-23: WARNING: Function
"for_each_child_of_node" should have of_node_put() before return around
line 936.
