Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work
falls into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be
moved into read-only memory (i.e. const) The recent work with Rust
has pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only
making things safer overall. This is the contuation of that work
(started last release with kobject changes) in moving struct
bus_type to be constant. We didn't quite make it for this release,
but the remaining patches will be finished up for the release after
this one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems"
[ Geert Uytterhoeven points out that that last sentence isn't true, and
that there's a pending report that has a fix that is queued up - Linus ]

The SPIB and DRMS capabilities are orthogonal to the DSP enablement
and can be used whether the stream is coupled or not.
The existing code partitioning makes limited sense, the capabilities
are parsed at the sound/hda level but helpers are located in
sound/hda/ext.
This patch moves all the SPIB/DRMS functionality to the sound/hda
layer. This reduces the complexity of the sound/hda/ext layer which is
now limited to handling the multi-link extensions and stream
coupling/decoupling helpers.
Note that this is an iso-functionality code move and rename, the
HDaudio legacy driver would need additional changes to make use of
these capabilities.

My esteemed colleagues keep using the same words for different things.
The multi-link structure needs to be handled whether the DSP is
enabled or not.
The host and link DMAs are only relevant when the DSP is enabled.
Things get convoluted when there's an ambiguity between the LOSIDV
settings in the multi-link register space and the selection of the
stream_tag for the link DMA.
Clarify with a rename that the static functions used are related to
the host and link DMAs only.
No functionality change, pure rename.

ASoC: Updates for v6.1
This has been a very quiet release for the core but quite a busy one for
drivers with a big crop of new drivers and lots of feature additions and
fixes to existing ones:
- A new string helper parse_int_array_user().
- Improvements to the SOF IPC4 code, especially around trace.
- Support for AMD Rembrant DSPs, AMD Pink Sardine ACP 6.2, Apple Silcon
systems, Everest ES8326, Intel Sky Lake and Kaby Lake, MediaTek
MT8186 support, NXP i.MX8ULP DSPs, Qualcomm SC8280XP, SM8250 and SM8450
and Texas Instruments SRC4392
There is a conflict with the conversion of I2C remove functions to void
in the cs42l42 driver which is fairly straightforward to resolve but
should be highlighted to Linus.
Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
This patchset solves a known issue with ES8336 platforms wrt MCLK
selection. Most of the devices use the MCLK0 signal, but some devices
do use the MCLK1 signal.
The MCLK is defined in the topology, it would be a nightmare to
generate more topology files just for one MCLK difference. With a
minor extension to the intel-nhlt library, the MCLK information can be
found by parsing the NHLT table, and we can override the mclk_id at
boot time.
The only known issues for this platform remain the detection of GPIO
and microphone connections, currently only possible with manual
quirks.
Thanks to Eugene J. Markow for testing this patchset.
SOF topologies hard-code the MCLK used for SSP connections. That was a
bad idea in hindsight, this information should really come from BIOS
and/or machine driver.
This patch introduces a helper to scan all SSP endpoints connected to
a codec, and all formats to see what MCLK is used. When BIT(0) of the
mdivc offset if set in the SSP blob, MCLK0 is used, and likewise when
BIT(1) is set MCLK1 is used.
The case where both MCLKs are used is possible but has never been seen
in practice so should be treated as an error by the caller.

ALSA: Drop hackish GFP giveaway for CONTINUOUS pages
This is a series of cleanup patches for dropping the current hackish
way of passing the GFP_* flags for CONTINOUS and VMALLOC memory
allocations. There are only three users for this legacy feature, and
all of them seem superfluous. And, if any driver requires the memory
restriction in future, it can now pass the proper device pointer for
specifying the DMA mask.

For sysfs outputs, it's safer to use a new helper, sysfs_emit(),
instead of the raw sprintf() & co. This patch replaces those usages
straightforwardly with new helpers, sysfs_emit() and sysfs_emit_at().

ASoC: More updates for v5.20
More updates that came in since the last pull request I sent, a series
of driver specific changes:
- Support for AMD RPL, some Intel platforms and Mediatek MT8186.
The TRACE_EVENT() macro is broken up into various parts to be efficient.
The TP_fast_assign() is just to record the event into the ring buffer, and
is to be done as fast as possible as this occurs during the actual running
of the code. The slower this is, the slower the code that is being traced
becomes.
The TP_printk() is processed when reading the tracing buffer. This is
considered the slow path. Any processing that can be moved from the
TP_fast_assign() to the TP_printk() should do so.
For some reason, the entire string processing of the trace events
hda_send_cmd, hda_get_response, and hda_unsol_event was moved from the
TP_printk() into the TP_fast_assign(). On top of that, the
__dynamic_array() was used with a fixed size of HDAC_MSG_MAX, which is
useless as a dynamic_array as it will always allocate HDAC_MSG_MAX bytes
on the ring buffer and even save that amount into the event (as it expects
the size to be dynamic, which using a fixed size defeats that purpose).
Instead, just save the necessary elements in the TP_fast_assign() and do
the string manipulation in the slow path.
The output should be the same.
