Currently, for AP MLD, the link ID is not provided when a NULL
packet is triggered to probe a station. For non-MLO stations connected
to an AP MLD, use the station's default link to send the NULL packets
and set addr2 and addr3 to the link address. For MLO stations, set the
link ID to unspecified to let the driver select the appropriate link.

Currently, when sending a NULL frame to probe a station, the band
information is derived from the chanctx_conf in the mac80211 vif's
bss_conf. However, for AP MLD, chanctx_conf is not assigned to the
vif's bss_conf; instead it is assigned on a per-link basis. As a result,
for AP MLD, sending a NULL packet to probe will trigger a warning.

The mwifiex_adapter_cleanup() function uses timer_delete()
(non-synchronous) for the wakeup_timer before the adapter structure is
freed. This is incorrect because timer_delete() does not wait for any
running timer callback to complete.
If the wakeup_timer callback (wakeup_timer_fn) is executing when
mwifiex_adapter_cleanup() is called, the callback will continue to
access adapter fields (adapter->hw_status, adapter->if_ops.card_reset,
etc.) which may be freed by mwifiex_free_adapter() called later in the
mwifiex_remove_card() path.
Use timer_delete_sync() instead to ensure any running timer callback has
completed before returning.

Add validation of the inner IPv4 packet tot_len and ihl fields parsed
from decrypted IPTFS payloads in __input_process_payload(). A crafted
ESP packet containing an inner IPv4 header with tot_len=0 causes an
infinite loop: iplen=0 leads to capturelen=min(0, remaining)=0, so the
data offset never advances and the while(data < tail) loop never
terminates, spinning forever in softirq context.
Reject inner IPv4 packets where tot_len < ihl*4 or ihl*4 < sizeof(struct
iphdr), which catches both the tot_len=0 case and malformed ihl values.
The normal IP stack performs this validation in ip_rcv_core(), but IPTFS
extracts and processes inner packets before they reach that layer.

In mwifiex_11n_aggregate_pkt(), skb_aggr is allocated via
mwifiex_alloc_dma_align_buf(). If mwifiex_is_ralist_valid() returns false,
the function currently returns -1 immediately without freeing the
previously allocated skb_aggr, causing a memory leak.
Since skb_aggr has not yet been queued via skb_queue_tail(), no other
references to this memory exist. Therefore, it has to be freed locally
before returning the error.
Fix this by calling mwifiex_write_data_complete() to free skb_aggr before
returning the error status.

The router NVM version is currently only available after the NVMem devices
have been registered. This is too late for firmware-dependent quirks that
are evaluated during tb_switch_add() before device registration.
Split router NVM handling into two phases:
- tb_switch_nvm_init() allocates the NVM object and reads the version
- tb_switch_nvm_add() registers the NVMem devices using the pre-read NVM
This makes the NVM major/minor version available before tb_check_quirks()
without changing when the NVMem devices are registered.

pci_epf_mhi_edma_read() and pci_epf_mhi_edma_write() start DMA
operations and wait for completion with a timeout.
On successful completion, they previously returned the remaining
timeout, which callers may treat as an error. In particular,
mhi_ep_ring_add_element(), which calls pci_epf_mhi_edma_write() via
mhi_cntrl->write_sync(), interprets any non-zero return value as
failure.
Return 0 on success instead of the remaining timeout to prevent
mhi_ep_ring_add_element() from treating successful completion as an
error.

For some parts, the DSP is kept running when in low power mode
(hibernation), leaving the firmware ALSA controls enabled, but the
registers are inaccessible. Attempts to access volatile firmware
controls whilst in this state would produce errors in the kernel log
due to a regmap_raw_read() into DSP registers whilst the regmap is in
cache_only.
To remove this error log, add a hibernating flag to indicate that the
controls are inaccessible, so we no longer try to read or write to the
registers whilst the regmap is in cache_only.
This would still produce an error when trying to read or write to these
controls, but this would be a different error (-EPERM instead of
-EBUSY), and would not produce a spurious error log in the kernel.
Upon wake from hibernation, the control caches are re-synced to the
hardware, if the DSP is running.

When regmap_field_alloc() fails, it can return an error. Specifically,
it will return PTR_ERR(-ENOMEM) when the allocation returns a NULL

if (player->clk_sel) {
// May dereference invalid pointer (-ENOMEM)
err = regmap_field_write(player->clk_sel, ...);
}
Ensure initialization fails by forwarding the errors from

Move the ASP register patches to a separate struct and apply this from the
ASP DAI probe() function so that the registers are only patched if the DAI
is part of a DAI link.
Some systems use the ASP as a special-purpose interconnect and on these
systems the ASP registers are configured by a third party (the firmware,
the BIOS, or another device using the amp's secondary host control
interface).
If the machine driver does not hook up the ASP DAI then the ASP registers
must be omitted from the patch to prevent overwriting the third party
configuration.
If the machine driver includes the ASP DAI in a DAI link, this implies that
the machine driver and higher components (such as alsa-ucm) are taking
ownership of the ASP. In this case the ASP registers are patched to known
defaults and the machine driver should configure the ASP.

ALSA controls should return 1 if the value in the control changed but the
control put operation fsl_easrc_set_reg() only returns 0 or a negative
error code, causing ALSA to not generate any change events. Add a suitable
check by using regmap_update_bits_check() with the underlying regmap, this
is more clearly and simply correct than trying to verify that one of the
generic ops is exactly equivalent to this one.

The deferred page initialization prevents debug objects from allocating
slab pages until the initialization is complete. That causes depletion of
the pool and disabling of debugobjects.
The reason is that debugobjects uses __GFP_HIGH for allocations as it might
be invoked from arbitrary contexts. When PREEMPT_COUNT is disabled there is
no way to know whether the context is safe to set __GFP_KSWAPD_RECLAIM.
This worked until v6.18. Since then allocations w/o a reclaim flag cause
new_slab() to end up in alloc_frozen_pages_nolock_noprof(), which returns
early when deferred page initialization has not yet completed.
Work around that when PREEMPT_COUNT is enabled as the preempt counter
allows debugobjects to add __GFP_KSWAPD_RECLAIM to the GFP flags when the
context is preemtible. When PREEMPT_COUNT is disabled the context is
unknown and the reclaim bit can't be set because the caller might hold
locks which might deadlock in the allocator.
That makes debugobjects depend on PREEMPT_COUNT || !DEFERRED_STRUCT_PAGE_INIT,
which limits the coverage slightly, but keeps it functional for most cases.

Pull locking fix from Ingo Molnar:
"Now that LLVM 22 has been released officially, require a release
version to use the new CONFIG_WARN_CONTEXT_ANALYSIS feature.
In particular this avoids the widely used Android clang 22.0.1
pre-release build which is known to be broken for this usecase"

All changes in drivers (well technically ses is enclosure services,
but its change is minor). The biggest is the write combining change
in lpfc followed by the additional NULL checks in mpi3mr.
