powerpc/pseries: add of_node_put() in dlpar_detach_node()
BugLink: https://bugs.launchpad.net/bugs/1818813 [ Upstream commit 5b3f5c40 ] The previous commit, "of: overlay: add missing of_node_get() in __of_attach_node_sysfs" added a missing of_node_get() to __of_attach_node_sysfs(). This results in a refcount imbalance for nodes attached with dlpar_attach_node(). The calling sequence from dlpar_attach_node() to __of_attach_node_sysfs() is: dlpar_attach_node() of_attach_node() __of_attach_node_sysfs() For more detailed description of the node refcount, see commit 68baf692 ("powerpc/pseries: Fix of_node_put() underflow during DLPAR remove").
