[PATCH] of: drop a reference on error in __of_attach_node_sysfs()

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

 



We add a new of_node_get() to this function, but we should drop the
reference if kobject_add().

Fixes: 5b2c2f5a0ea3 ("of: overlay: add missing of_node_get() in __of_attach_node_sysfs")

>From static analysis.  Maybe we should just call of_node_get() right
before we return 0?
