drm/i915/audio: Fix audio detection issue on GLK
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) Cc: <stable@vger.kernel.org> # b651bd2a3ae3 ("drm/i915/audio: Fix audio enumeration issue on BXT") Cc: <stable@vger.kernel.org> Signed-off-by: Gaurav K Singh <gaurav.k.singh@intel.com> Reviewed-by: Abhay Kumar <abhay.Kumar@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/1523989338-29677-1-git-send-email-gaurav.k.singh@intel.com (cherry picked from commit 8221229046e862977ae93ec9d34aa583fbd10397) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
