4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira at intel.com>
commit 21d6e0bde50713922a6520ef84e5fd245b05d468 upstream.
An error in the condition for avoiding the call to intel_hpd_poll_init()
for valleyview and cherryview from intel_runtime_suspend() caused it to
be called unconditionally. Fix it.
