Subject: [PATCH 3.18 04/50] powerpc/pseries: Fix of_node_put() underflow during reconfig remove
Date: Fri, 4 Aug 2017 16:15:50 -0700 [thread overview]
Message-ID: <20170804231551.085026886@linuxfoundation.org> (raw)
In-Reply-To: <20170804231550.830518786@linuxfoundation.org>
3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Laurent Vivier <lvivier@redhat.com>
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")
