There is a small typo in phm_wait_on_indirect_register().
Swap mask and value arguments provided to phm_wait_on_register() so that
they satisfy the function signature and actual usage scheme.
Found by Linux Verification Center (linuxtesting.org) with Svace static
analysis tool.
In practice this doesn't fix any issues because the only place this
function is used uses the same value for the value and mask.

Pull drm updates from Dave Airlie:
"As part of building up nova-core/nova-drm pieces we've brought in some
rust abstractions through this tree, aux bus being the main one, with
devres changes also in the driver-core tree. Along with the drm core
abstractions and enough nova-core/nova-drm to use them. This is still
all stub work under construction, to build the nova driver upstream.
The other big NVIDIA related one is nouveau adds support for
Hopper/Blackwell GPUs, this required a new GSP firmware update to
570.144, and a bunch of rework in order to support multiple fw
interfaces.
There is also the introduction of an asahi uapi header file as a
precursor to getting the real driver in later, but to unblock
userspace mesa packages while the driver is trapped behind rust
enablement.
Otherwise it's the usual mixture of stuff all over, amdgpu, i915/xe,

-------
* Reduce open-coded use of ratelimit_state structure fields.
* Convert the ->missed field to atomic_t.
* Count misses that are due to lock contention.
* Eliminate jiffies=0 special case.
* Reduce ___ratelimit() false-positive rate limiting (Petr Mladek).
* Allow zero ->burst to hard-disable rate limiting.
* Optimize away atomic operations when a miss is guaranteed.
* Warn if ->interval or ->burst are negative (Petr Mladek).
* Simplify the resulting code.
A smoke test and stress test have been created, but they are not yet ready
for mainline. With luck, we will offer them for the v6.17 merge window.

The previous patch removed smu_mode2_reset_is_support()
which was the only function to call through the mode2_reset_is_support()
method pointer.
Remove the remaining functions that were assigned to it
and the pointer itself.
