Enable USB driver for s32g2. This chip has an errata ERR050474[1]
so we need to set S32G_UCMALLBE to avoid some memory corruption. I
have include the description below:
ERR050474: USB : USB data may be corrupted if transaction size is
non-multiple of 32bits
Description
When USB issues narrow length transfers i.e. AHB transaction size is less
than 4bytes, data for that transaction will get corrupted. Narrow length
transactions can occur if the transaction size is non-multiple of four
bytes, error scenarios terminate the transactions early or if the address
offset programmed in QTD is 4 Byte unaligned. This happens because the
SoC NOC is not able to handle the byte strobes generated by USB controller
and is dependent on its internally generates byte strobes.
Workaround
Narrow transfers work properly on bypassing USB controller’s byte
generation logic. This can be done by setting UCMALLBE (bit 15, USB Core
Master All Byte Enable) bit of UOTGNC_CR.

Add the compatible strings for the NXP s32g2 and s32g3. These chips

device has an errata ERR050474 which requires a special flag to be set

Commit 24729b307e ("usb: gadget: f_fs: Fix race between aio_cancel()
and AIO request complete") moved the call to usb_ep_free_request() from
ffs_epfile_async_io_complete() to ffs_user_copy_worker().
In ffs_user_copy_worker(), ki_complete() is called before
usb_ep_free_request(). Once ki_complete() returns, ffs_aio_cancel() can
no longer be invoked for the completed kiocb, as ki_complete() removes it
from the &ctx->active_reqs list in aio.c. ffs_aio_cancel() only applies
to kiocb instances still present on this list.
The potential race between ki_complete() and ffs_aio_cancel() is already
guarded by the &ctx->ctx_lock spinlock in aio.c.
As a result, there is no race condition between the usb_ep_dequeue() call
in ffs_aio_cancel() and the usb_ep_free_request() call in
ffs_user_copy_worker(). Consequently, the spin lock/unlock operations on
&io_data->ffs->eps_lock are no longer necessary.

Now that the TRB reclaim logic always inspects the TRB's CHN (Chain) bit
directly to determine whether a TRB is part of a chain, the explicit
'chain' parameter passed into dwc3_gadget_ep_reclaim_completed_trb()
is no longer necessary.
This cleanup simplifies the reclaim code by avoiding duplication of
chain state tracking, and makes the reclaim logic rely entirely on the
hardware descriptor flags — which are already present and accurate at
this stage.
No functional changes intended.

In hidg_bind(), if alloc_workqueue() fails after usb_assign_descriptors()
has successfully allocated the USB descriptors, the current error handling
does not call usb_free_all_descriptors() to free the allocated descriptors,
resulting in a memory leak.
Restructure the error handling by adding proper cleanup labels:
- fail_free_all: cleans up workqueue and descriptors
- fail_free_descs: cleans up descriptors only
- fail: original cleanup for earlier failures
This ensures that allocated resources are properly freed in reverse order
of their allocation, preventing the memory leak when alloc_workqueue() fails.

This patch is a mitigation to prevent the A-MSDU spoofing vulnerability
for mesh networks. The initial update to the IEEE 802.11 standard, in
response to the FragAttacks, missed this case (CVE-2025-27558). It can
be considered a variant of CVE-2020-24588 but for mesh networks.
This patch tries to detect if a standard MSDU was turned into an A-MSDU
by an adversary. This is done by parsing a received A-MSDU as a standard
MSDU, calculating the length of the Mesh Control header, and seeing if
the 6 bytes after this header equal the start of an rfc1042 header. If
equal, this is a strong indication of an ongoing attack attempt.
This defense was tested with mac80211_hwsim against a mesh network that
uses an empty Mesh Address Extension field, i.e., when four addresses
are used, and when using a 12-byte Mesh Address Extension field, i.e.,
when six addresses are used. Functionality of normal MSDUs and A-MSDUs
was also tested, and confirmed working, when using both an empty and
12-byte Mesh Address Extension field.
It was also tested with mac80211_hwsim that A-MSDU attacks in non-mesh
networks keep being detected and prevented.
Note that the vulnerability being patched, and the defense being
implemented, was also discussed in the following paper and in the
following IEEE 802.11 presentation:

mac80211 identifies a short beacon by the presence of the next
TBTT field, however the standard actually doesn't explicitly state that
the next TBTT can't be in a long beacon or even that it is required in
a short beacon - and as a result this validation does not work for all
vendor implementations.
The standard explicitly states that an S1G long beacon shall contain
the S1G beacon compatibility element as the first element in a beacon
transmitted at a TBTT that is not a TSBTT (Target Short Beacon
Transmission Time) as per IEEE80211-2024 11.1.3.10.1. This is validated
by 9.3.4.3 Table 9-76 which states that the S1G beacon compatibility
element is only allowed in the full set and is not allowed in the
minimum set of elements permitted for use within short beacons.
Correctly identify short beacons by the lack of an S1G beacon
compatibility element as the first element in an S1G beacon frame.
