      drm/i915, HD-audio: Don't continue probing when nomodeset is given · 74b0c2d7
      Takashi Iwai 提交于
      When a machine is booted with nomodeset option, i915 driver skips the
      whole initialization.  Meanwhile, HD-audio tries to bind wth i915 just
      by request_symbol() without knowing that the initialization was
      skipped, and eventually it hits WARN_ON() in i915_request_power_well()
      and i915_release_power_well() wrongly but still continues probing,
      even though it doesn't work at all.
      
      In this patch, both functions are changed to return an error in case
      of uninitialized state instead of WARN_ON(), so that HD-audio driver
      can give up HDMI controller initialization at the right time.
