Subject: [PATCH AUTOSEL for 4.9 039/293] cpuidle: dt: Add missing
 'of_node_put()'

From: Christophe Jaillet <christophe.jaillet@...adoo.fr>

[ Upstream commit b2cdd8e1b54849477a32d820acc2e87828a38f3d ]

'of_node_put()' should be called on pointer returned by
'of_parse_phandle()' when done. In this function this is done in all path
except this 'continue', so add it.

Fixes: 97735da074fd (drivers: cpuidle: Add status property to ARM idle states)
