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.

That could be written as

which in turn could just be written as
if (!IS_GEN9(dev_priv))

will be present in gen 10 too, and whether this should just become

+1. I opened here to exactly add same comment.
I am checking with DINQ and without this patch for GLK it can enumerate
HDA codec. Ofcourse after cdclk fix.
