4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Laurent Vivier <lvivier@xxxxxxxxxx>
commit 4fd1bd443e80b12f0a01a45fb9a793206b41cb72 upstream.
As for commit 68baf692c435 ("powerpc/pseries: Fix of_node_put()
underflow during DLPAR remove"), the call to of_node_put() must be
removed from pSeries_reconfig_remove_node().
dlpar_detach_node() and pSeries_reconfig_remove_node() both call
of_detach_node(), and thus the node should not be released in both
cases.
Fixes: 0829f6d1f69e ("of: device_node kobject lifecycle fixes")
