In snd_hdac_device_init pm_runtime_set_active is called to
increase child_count in parent device. But when it is failed
to build connection with GPU for one case that integrated
graphic gpu is disabled, snd_hdac_ext_bus_device_exit will be
invoked to clean up a HD-audio extended codec base device. At
this time the child_count of parent is not decreased, which
makes parent device can't get suspended.
This patch calls pm_runtime_set_suspended to decrease child_count
in parent device in snd_hdac_device_exit to match with
snd_hdac_device_init. pm_runtime_set_suspended can make sure that
it will not decrease child_count if the device is already suspended.

The PCM OSS mulaw plugin has a check of the format of the counter part
whether it's a linear format. The check is with snd_BUG_ON() that
emits WARN_ON() when the debug config is set, and it confuses
syzkaller as if it were a serious issue. Let's drop snd_BUG_ON() for
avoiding that.
While we're at it, correct the error code to a more suitable, EINVAL.

Following Christian Lachner's patch for Gigabyte X570-based motherboards,
also patch the MSI X570-A PRO motherboard; the ALC1220 codec requires the
same workaround for Clevo laptops to enforce the DAC/mixer connection
path. Set up a quirk entry for that.
I suspect most if all X570 motherboards will require similar patches.

When system is suspended with active audio playback to HDMI/DP, two
alternative sequences can happen at resume:
a) monitor is detected first and ALSA prepare follows normal
stream setup sequence, or
b) ALSA prepare is called first, but monitor is not yet detected,
so PCM is restarted without a pin,
In case of (b), on i915 systems, haswell_verify_D0() is not called at
resume and the pin power state may be incorrect. Result is lack of audio
after resume with no error reported back to user-space.
Fix the problem by always verifying converter and pin state in the
i915_pin_cvt_fixup().

The Galaxy Book Ion NT950XCJ-X716A (15 inches) uses the same ALC298
codec as other Samsung laptops which have the no headphone sound bug. I
confirmed on my own hardware that this fixes the bug.
This also correct the model name for the 13 inches version. It was
incorrectly referenced as NT950XCJ-X716A in commit e17f02d05. But it
should have been NP930XCJ-K01US.

The commit 51ab5d77dcb8 ("ALSA: usb-audio: Properly match with audio
interface class") converted the quirk entries that have both vid/pid
pair and bInterface fields to match with all those with a new macro
USB_AUDIO_CLASS(). However, it turned out that those are false
conversions; all those (but the unknown KeithMcMillen device) are
actually with vendor-specific interface class, hence the conversions
broke the matching.
This patch corrects those entries to the right one,
USB_DEVICE_VENDOR_SPEC() (and USB_DEVICE() for KeithMcMillen to be
sure), and drop the unused USB_AUDIO_CLASS macro again.

Pull powerpc fixes from Michael Ellerman:
- Add perf support for emitting extended registers for power10.
- A fix for CPU hotplug on pseries, where on large/loaded systems we
may not wait long enough for the CPU to be offlined, leading to
crashes.
- Addition of a raw cputable entry for Power10, which is not required
to boot, but is required to make our PMU setup work correctly in
guests.
- Three fixes for the recent changes on 32-bit Book3S to move modules
into their own segment for strict RWX.
- A fix for a recent change in our powernv PCI code that could lead to
crashes.
- A change to our perf interrupt accounting to avoid soft lockups when
using some events, found by syzkaller.
- A change in the way we handle power loss events from the hypervisor
on pseries. We no longer immediately shut down if we're told we're
running on a UPS.
- A few other minor fixes.

Pull x86 fix from Thomas Gleixner:
"A single fix for x86 which removes the RDPID usage from the paranoid
entry path and unconditionally uses LSL to retrieve the CPU number.
RDPID depends on MSR_TSX_AUX. KVM has an optmization to avoid
expensive MRS read/writes on VMENTER/EXIT. It caches the MSR values
and restores them either when leaving the run loop, on preemption or
when going out to user space. MSR_TSX_AUX is part of that lazy MSR
set, so after writing the guest value and before the lazy restore any
exception using the paranoid entry will read the guest value and use
it as CPU number to retrieve the GSBASE value for the current CPU when
FSGSBASE is enabled. As RDPID is only used in that particular entry
path, there is no reason to burden VMENTER/EXIT with two extra MSR
writes. Remove the RDPID optimization, which is not even backed by
numbers from the paranoid entry path instead"
