On SKL+ Intel platforms, the driver selection is handled by the snd_intel_dspcfg, and when the HDaudio legacy driver is not selected, be it with the auto-selection or user preferences with a kernel parameter, the probe aborts with no logs, only a -ENODEV return value. Having no dmesg trace, even with dynamic debug enabled, makes support more complicated than it needs to be, and even experienced users can be fooled. A simple dev_dbg() trace solves this problem.

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.

Kai Vehmanen authored
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 e17f02d0. But it should have been NP930XCJ-K01US.

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" * tag 'x86-urgent-2020-08-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/entry/64: Do not use RDPID in paranoid entry to accomodate KVM

Avid Adrenaline is reported that ALSA firewire-digi00x driver is bound to. However, as long as he investigated, the design of this model is hardly similar to the one of Digi 00x family.

Tascam FE-8 is known to support communication by asynchronous transaction only. The support can be implemented in userspace application and snd-firewire-ctl-services project has the support. However, ALSA firewire-tascam driver is bound to the model. This commit changes device entries so that the model is excluded. In a commit 53b3ffee ("ALSA: firewire-tascam: change device probing processing"), I addressed to the concern that version field in configuration differs depending on installed firmware. However, as long as I checked, the version number is fixed. It's safe to return version number back to modalias.

When adding a new fd to an epoll, and that this new fd is an epoll fd itself, we recursively scan the fds attached to it to detect cycles, and add non-epool files to a "check list" that gets subsequently parsed. However, this check list isn't completely safe when deletions can happen concurrently. To sidestep the issue, make sure that a struct file placed on the check list sees its f_count increased, ensuring that a concurrent deletion won't result in the file disapearing from under our feet.
