[PATCH] drm/i915: Initialize audio only when display is present

[PATCH] drm/i915: Initialize audio only when display is present

[Mika Kahola]

At least in Coffee Lake it happens that we start initiliazing audio when
no display is connected. This was discovered by CI when running IGT test
case

drv_module_reload --r basic-no-display

The issue here is that the 'intel_device_info_runtime_init()' sets
num_pipes to 0 but before this happens the audio part has already started
to initialize itself. Later on the num_pipes is updated to 0 in
intel_device_info_runtime_init() and we hit that when audio part is digging
out ELD. This causes a warning in dmesg. To fix this issue, let's register
the audio driver only in a case when display is enabled.

runtime_init happens twice? (I am confused by this pair of sentences.)

INTEL_INFO()->num_ports == 0 is the derived value that includes cases
where the display is fused off as well.

This is tricky. i915_audio_component_get_eld() gets called from a sound
driver. Even though, I disable intel_audio_init() call, these num_pipes
warnings keep popping up in dmesg like this.

Ask for a kasan run. I don't see where i915 is unbound during cleanup.
component_del() only unbinds the master, and not itself. As I read the
code it seems like the old i915 device is not uncoupled.

First time I dipped my toe into the component code so take that with a
pinch of salt.
