Several new features here:
- Virtio find vqs API has been reworked
(required to fix the scalability issue we have with
adminq, which I hope to merge later in the cycle)
- vDPA driver for Marvell OCTEON
- virtio fs performance improvement
- mlx5 migration speedups
Fixes, cleanups all over the place.

Otherwise, unless tpm2_sessions_init() was called, a call can cause NULL

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
While at it, also remove commas after the sentinel entries.

When there are rng sources registering at the hwrng core via
hwrng_register() a struct hwrng is delivered. There is a quality
field in there which is used to decide which of the registered
hw rng sources will be used by the hwrng core.
With commit 16bdbae39428 ("hwrng: core - treat default_quality as
a maximum and default to 1024") there came in a new default of
1024 in case this field is empty and all the known hw rng sources
at that time had been reworked to not fill this field and thus
use the default of 1024.
The code choosing the 'better' hw rng source during registration
of a new hw rng source has never been adapted to this and thus
used 0 if the hw rng implementation does not fill the quality field.
So when two rng sources register, one with 0 (meaning 1024) and
the other one with 999, the 999 hw rng will be chosen.
As the later invoked function hwrng_init() anyway adjusts the
quality field of the hw rng source, this adjustment is now done
during registration of this new hw rng source.
Tested on s390 with two hardware rng sources: crypto cards and
trng true random generator device driver.

include/linux/pm_runtime.h pm_runtime_get_sync() description suggests to
... consider using pm_runtime_resume_and_get() instead of it, especially
if its return value is checked by the caller, as this is likely to result
in cleaner code.
This is indeed better, switch to pm_runtime_resume_and_get() which
correctly suspends the device again in case of failure. Also add error
checking into the RNG driver in case pm_runtime_resume_and_get() does
fail, which is currently not done, and it does detect sporadic -EACCES
error return after resume, which would otherwise lead to a hang due to
register access on un-resumed hardware. Now the read simply errors out

A potential deadlock was reported with the config file at
https://web.archive.org/web/20240522052129/https://0x0.st/XPN_.txt
In this particular configuration, the deadlock doesn't exist because
the warning triggered at a point before modules were even available.
However, the deadlock can be real because any module loaded would
invoke async_synchronize_full.
The issue is spurious for software crypto algorithms which aren't
themselves involved in async probing. However, it would be hard to
avoid for a PCI crypto driver using async probing.
In this particular call trace, the problem is easily avoided because
the only reason the module is being requested during probing is the
add_early_randomness call in the hwrng core. This feature is
vestigial since there is now a kernel thread dedicated to doing
exactly this.
So remove add_early_randomness as it is no longer needed.

Here is the big set of char/misc and other driver subsystem updates for
6.10-rc1. Nothing major here, just lots of new drivers and updates for
apis and new hardware types. Included in here are:
- big IIO driver updates with more devices and drivers added
- fpga driver updates
- hyper-v driver updates
- uio_pruss driver removal, no one uses it, other drivers control the
same hardware now
- binder minor updates
- mhi driver updates
- excon driver updates
- counter driver updates
- accessability driver updates
- coresight driver updates
- other hwtracing driver updates
- nvmem driver updates
- slimbus driver updates
- spmi driver updates
- other smaller misc and char driver updates
All of these have been in linux-next for a while with no reported
issues.
