Mostly driver changes this time:
 - new driver mm81x for an S1G device
 - new driver nxpwifi for NXP devices
   (mostly forked off from mwifiex)
 - ath12k: much kernel infrastructure integration work
 - brcmfmac: DPP support, some Cypress part update
 - nl80211: per-link statistics support

The mmcblk.perdev_minors module parameter is parsed as a signed int and
is used during mmc_blk_init() to compute the number of supported block
devices.

Passing perdev_minors=0 makes the init path divide by zero when it
computes max_devices. Negative values are invalid as well and would make
max_devices negative before it is later used as an IDA limit.

Reject non-positive perdev_minors values before registering any mmcblk
resources.

The NXP IW61x series SDIO chipset identifies itself with a base card ID
(0x0204) during the initial MMC bus scan, while the specific WLAN
function reports a different ID (0x0205).

To ensure that the MMC_QUIRK_BLKSZ_FOR_BYTE_MODE quirk is correctly
inherited by all SDIO functions (including Wi-Fi), it must be attached
to the base card ID at the core level.

Add the SDIO_DEVICE_ID_NXP_IW61X_BASE definition and apply the required
fixup in the SDIO quirk table.

Merge the mmc fixes for v7.2-rc[n] into the next branch, to allow them to

release.

Since commit 7852028a35f0 ("mmc: block: register RPMB partition with
the RPMB subsystem"), each mmc RPMB partition is represented by two
device objects:
 - the mmc-owned device (`rpmb->dev`, backing the legacy /dev/mmcblkXrpmb
   char device) and
 - the rpmb-core device (`rdev`, backing /dev/rpmbN).

The child RPMB device holds a reference to its parent, so the
parent's release callback cannot be invoked if the child device
is still registered.

Remove rpmb_dev_unregister() from the parent release handler and
unregister the child RPMB device in the remove path before tearing
down the parent device.

Also delete the extra blank line between mmc_blk_remove_rpmb_part()
and {.

Fix logic issues introduced by the kzalloc_flex() conversion in
mmc_test_alloc_mem() due to interaction with the __counted_by
annotation on the flexible array.

Bounds-checking sanitizers rely on the counter field reflecting the
allocated array size before any array access occurs. However, use
mem->cnt both as the allocation size and as the runtime insertion
index, causing incorrect indexing and potentially invalid bounds
tracking.

Initialize mem->cnt to the maximum allocated number of segments
immediately after kzalloc_flex(), then use a separate local index
variable to track successfully allocated entries. Update mem->cnt to
the actual number of initialized elements before returning or entering
the cleanup path.

Also rewrite mmc_test_free_mem() to use a forward for-loop, improving
readability and ensuring only initialized entries are freed.

  ...

numa_node in blk_mq_hw_ctx and the matching argument of
blk_mq_ops::init_request can be NUMA_NO_NODE (-1).  Declared as
unsigned int, NUMA_NO_NODE becomes UINT_MAX and walks off
nvme_dev::descriptor_pools[] on CONFIG_NUMA=n [1].

Switch the field and the callback prototype to int and update all
in-tree init_request implementations.  No functional change:
cpu_to_node(), kmalloc_node() and blk_alloc_flush_queue() already
take int.
