The HD-audio CORB/RIRB communication was programmed in a way that was documented in the reference in decades ago, which is essentially a polling in the waiter side. It's working fine but costs CPU cycles on some platforms that support only slow communications. Also, for some platforms that had unreliable communications, we put longer wait time (2 ms), which accumulate quite long time if you execute many verbs in a shot (e.g. at the initialization or resume phase). This patch attempts to improve the situation by introducing the standard waitqueue in the RIRB waiter side instead of polling. The test results on my machine show significant improvements. The time spent for "cat /proc/asound/card*/codec#*" were changed like: * Intel SKL + Realtek codec before the patch: 0.00user 0.04system 0:00.10elapsed 40.0%CPU after the patch: 0.00user 0.01system 0:00.10elapsed 10.0%CPU * Nvidia GP107GL + Nvidia HDMI codec before the patch: 0.00user 0.00system 0:02.76elapsed 0.0%CPU after the patch: 0.00user 0.00system 0:00.01elapsed 17.0%CPU So, for Intel chips, the total time is same, while the total time is greatly reduced (from 2.76 to 0.01s) for Nvidia chips. The only negative data here is the increase of CPU time for Nvidia, but this is the unavoidable cost for faster wakeups, supposedly.

Nicholas Johnson reports a null pointer deref as well as a refcount underflow upon hot-removal of a Thunderbolt-attached AMD eGPU. He's bisected the issue down to commit 586bc4aa ("ALSA: hda/hdmi - fix vgaswitcheroo detection for AMD"). The commit iterates over PCI devices using pci_get_class() and unreferences each device found, even though pci_get_class() subsequently unreferences the device as well. Fix it.

The loop optimizer seems to go astray here, and produces some warnings that don't seem valid. Still, the code can be simplified -- just clear the whole array at the beginning, and fill in whatever values are valid on the platform.
