ASoC: Fixes for v5.1

A few core fixes along with the driver specific ones, mainly fixing
small issues that only affect x86 platforms for various reasons (their
unusual machine enumeration mechanisms mainly, plus a fix for error
handling in topology).

There's some of the driver fixes that look larger than they are, like
the hdmi-codec changes which resulted in an indentation change, and most
of the other large changes are for new drivers like the STM32 changes.

Pull libnvdimm updates from Dan Williams:
"The bulk of this has been in -next since before the merge window
opened, with no known collisions / issues reported.

The only detail worth noting, outside the summary below, is that the
"libnvdimm-start-pad" topic has been truncated to just cleanups and
small fixes. The full topic branch would have doubled down on hacks
around the "section alignment" limitation of the core-mm, instead
effort is now being spent to address that root issue in the memory
hotplug implementation for v5.2.

- Fix nfit-bus command submission regression

- Support retrieval of short-ARS results if the ARS state is
"requires continuation", and even if the "no_init_ars" module
parameter is specified

- Allow busy-polling of the kernel ARS state by allowing root to
reset the exponential back-off timer

- Filter potentially stale ARS results by tracking query-ARS relative
to the previous start-ARS

- Enhance dax_device alignment checks

- Add support for the Hyper-V family of device-specific-methods
(DSMs)

- Add several fixes and workarounds for Hyper-V compatibility

- Fix support to cache the dirty-shutdown-count at init"

nfit/ars: Allow root to busy-poll the ARS state machine

The ARS implementation implements exponential back-off on the poll
interval to prevent high-frequency access to the DIMM / platform
interface. Depending on when the ARS completes the poll interval may
exceed the completion event by minutes. Allow root to reset the timeout
each time it probes the status. A one-second timeout is still enforced,
but root can otherwise can control the poll interval.

Merge tag 'libnvdimm-for-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm updates from Dan Williams:
"The vast bulk of this update is the new support for the security
capabilities of some nvdimms.

The userspace tooling for this capability is still a work in progress,
but the changes survive the existing libnvdimm unit tests. The changes
also pass manual checkout on hardware and the new nfit_test emulation
of the security capability.

The touches of the security/keys/ files have received the necessary
acks from Mimi and David. Those changes were necessary to allow for a
new generic encrypted-key type, and allow the nvdimm sub-system to
lookup key material referenced by the libnvdimm-sysfs interface.

Summary:

- Add support for the security features of nvdimm devices that
implement a security model similar to ATA hard drive security. The
security model supports locking access to the media at
device-power-loss, to be unlocked with a passphrase, and
secure-erase (crypto-scramble).

Unlike the ATA security case where the kernel expects device
security to be managed in a pre-OS environment, the libnvdimm
security implementation allows key provisioning and key-operations
at OS runtime. Keys are managed with the kernel's encrypted-keys
facility to provide data-at-rest security for the libnvdimm key
material. The usage model mirrors fscrypt key management, but is
driven via libnvdimm sysfs.

- Miscellaneous updates for api usage and comment fixes"
