For Haswell and Broadwell, if the display power well has been disabled, the display audio controller divider values EM4 M VALUE and EM5 N VALUE will have been lost. The CDCLK frequency is required for reprogramming them to generate 24MHz HD-A link BCLK. So provide a private interface for the audio driver to query CDCLK. This is a stopgap solution until a more generic interface between audio and display drivers has been implemented.

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.

The modeset helpers and the probing helpers a independent and e.g. i915 uses the probing stuff but has its own modeset infrastructure. It hence makes to split this up. While at it add a DOC: comment for the probing libraray. It would be rather neat to pull some of the DocBook documenting these two helpers into in-line DOC: comments. But unfortunately kerneldoc doesn't support markdown or something similar to make nice-looking documentation, so the current state is better.
