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.
