If anyone has any objections, please let me know. ------------------ From: Gaurav K Singh 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: # b651bd2a3ae3 ("drm/i915/audio: Fix audio enumeration issue on BXT") Cc: Signed-off-by: Gaurav K Singh Reviewed-by: Abhay Kumar Signed-off-by: Jani Nikula 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 Signed-off-by: Greg Kroah-Hartman --- drivers/gpu/drm/i915/intel_audio.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/drivers/gpu/drm/i915/intel_audio.c +++ b/drivers/gpu/drm/i915/intel_audio.c @@ -729,7 +729,7 @@ static void i915_audio_component_codec_w struct drm_i915_private *dev_priv = kdev_to_i915(kdev); u32 tmp; - if (!IS_GEN9_BC(dev_priv)) + if (!IS_GEN9(dev_priv)) return; i915_audio_component_get_power(kdev);
