4.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gaurav K Singh <gaurav.k.singh@xxxxxxxxx>
commit b4615730530be85fc45ab4631c2ad6d8e2d0b97d upstream.
On Geminilake, sometimes audio card is not getting
detected after reboot. This is a spurious issue happening on
Geminilake. HW codec and HD audio controller link was going
out of sync for which there was a fix in i915 driver but
was not getting invoked for GLK. Extending this fix to GLK as well.
Tested by Du,Wenkai on GLK board.
Bspec: 21829
v2: Instead of checking GEN9_BC, BXT and GLK macros, use IS_GEN9 macro (Jani N)
