Series sound: Use -EPROBE_DEFER instead of i915 module loading. | expand

Commit Message

Maarten Lankhorst Oct. 4, 2023, 2:55 p.m. UTC 
Now that we can use -EPROBE_DEFER, it's no longer required to spin off
the snd_hdac_i915_init into a workqueue.

Use the -EPROBE_DEFER mechanism instead, which must be returned in the
probe function.

The previously added probe_early can be used for this,
and we also use the newly added remove_late for unbinding afterwards.
