powerpc/pseries: add of_node_put() in dlpar_detach_node()
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 68baf692c435 ("powerpc/pseries: Fix of_node_put() underflow during DLPAR remove"). Tested-by: Alan Tull <atull@kernel.org> Acked-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Frank Rowand <frank.rowand@sony.com>
