Okay, so I can see the following get_edid functions:

  intel_lvds_get_edid()
  intel_crt_get_edid()
  intel_sdvo_get_edid()
  intel_dp_get_edid()

In the hdmi case, drm_get_edid() is called in two places:
intel_hdmi_detect() and intel_hdmi_detect_audio(); should I factor out
something into a corresponding intel_hdmi_get_edid() function?

Now, in i915_switcheroo_reprobe(), I need to call all these functions,
right? They all accept a a generic drm_connector and an specific
i2c_adapter. But how do I do that without exporting each of these
functions and their adapters?

Thanks.
