Commit 4846300ba8 ("rust: derive `Zeroable` for all structs & unions
generated by bindgen where possible") automatically derives
`MaybeZeroable` for all bindings. This is better than selectively
deriving `Zeroable` as it ensures all types that can implement
`Zeroable` do.
Regenerate the nova-core bindings so they benefit from this, and remove
a now unneeded implementation of `Zeroable`.

The size of messages' payload is miscalculated, leading to extra data
passed to the message handler. While this is not a problem with our
current set of commands, others with a variable-length payload may
misbehave. Fix this by introducing a method returning the payload size

RUST_FW_LOADER_ABSTRACTIONS was depended on by NOVA_CORE, but NOVA_CORE
is selected by DRM_NOVA. This creates a situation where, if DRM_NOVA is
selected, NOVA_CORE gets enabled but not RUST_FW_LOADER_ABSTRACTIONS,
which results in a build error.
Since the firmware loader is an implementation detail of the driver, it
should be enabled along with it, so change the "depends on" to a
"select".

Initializing automatic __free variables to NULL without need (e.g.
branches with different allocations), followed by actual allocation is
in contrary to explicit coding rules guiding cleanup.h:
"Given that the "__free(...) = NULL" pattern for variables defined at
the top of the function poses this potential interdependency problem the
recommendation is to always define and assign variables in one statement
and not group variable definitions at the top of the function when
__free() is used."
Code does not have a bug, but is less readable and uses discouraged
coding practice, so fix that by moving declaration to the place of
assignment.

Some platforms expose more than 32 operating performance points (OPPs)
per performance domain via the SCMI performance protocol, but the
driver currently limits the number of OPPs it can handle to 32 via
MAX_OPPS.
Bump MAX_OPPS to 64 so that these platforms can register all their
performance levels. This is an internal limit in the driver only and
does not affect the SCMI protocol ABI.
64 is chosen as the next power of two above the existing limit.

This code to check whether the selector is valid and if the item has
already been recorded in the array can be moved to the
scmi_pinctrl_get_function_info() type functions. That way it's in
one place instead of duplicated in each of the callers.
Remove the check for if "pi->nr_groups == 0" because if that were the
case then "selector >= pi->nr_groups" would already be true. It already
was not checked for the pin case so this makes things a bit more uniform.
Also remove the check for if (!pin) since pin is an offset into the

Add dma_set_mask(), dma_set_coherent_mask(), dma_map_sgtable(), and

Note that when CONFIG_HAS_DMA is enabled, they are included in both

Commit 469c1c9eb6 ("kernel-doc: Issue warnings that were silently

Warning: drivers/gpu/drm/i915/intel_wakeref.h:156 expecting prototype
for __intel_wakeref_put(). Prototype was for INTEL_WAKEREF_PUT_ASYNC()
instead
Arguably kernel-doc should be able to handle this, as it's valid C, but
having the flags defined between the function declarator and the body is
just asking for trouble. Move the INTEL_WAKEREF_PUT_* macros away from
there, making kernel-doc's life easier.
While at it, reduce the unnecessary abstraction levels by removing the
enum, and append _MASK to INTEL_WAKEREF_PUT_DELAY for clarity.

When userspace brings down and deletes a non-transmitted profile,
it is expected to send a new updated Beacon template for the
transmitted profile of that multiple BSSID (MBSSID) group which
does not include the removed profile in MBSSID element. This
update comes via NL80211_CMD_SET_BEACON.
Such updates work well as long as the group continues to have at
least one non-transmitted profile as NL80211_ATTR_MBSSID_ELEMS
is included in the new Beacon template.
But when the last non-trasmitted profile is removed, it still
gets included in Beacon templates sent to driver. This happens
because when no MBSSID elements are sent by the userspace,
ieee80211_assign_beacon() ends up using the element stored from
earlier Beacon template.
Do not copy old MBSSID elements, instead userspace should always
include these when applicable.

Beacon frames are required to be sent to the broadcast address, see IEEE
Std 802.11-2020, 11.1.3.1 ("The Address 1 field of the Beacon .. frame
shall be set to the broadcast address"). A unicast Beacon frame might be
used as a targeted attack to get one of the associated STAs to do
something (e.g., using CSA to move it to another channel). As such, it
is better have strict filtering for this on the received side and
discard all Beacon frames that are sent to an unexpected address.
This is even more important for cases where beacon protection is used.
The current implementation in mac80211 is correctly discarding unicast
Beacon frames if the Protected Frame bit in the Frame Control field is
set to 0. However, if that bit is set to 1, the logic used for checking
for configured BIGTK(s) does not actually work. If the driver does not
have logic for dropping unicast Beacon frames with Protected Frame bit
1, these frames would be accepted in mac80211 processing as valid Beacon
frames even though they are not protected. This would allow beacon
protection to be bypassed. While the logic for checking beacon
protection could be extended to cover this corner case, a more generic
check for discard all Beacon frames based on A1=unicast address covers
this without needing additional changes.
Address all these issues by dropping received Beacon frames if they are
sent to a non-broadcast address.

qcom_swrm_stream_alloc_ports() already uses cleanup.h but also has goto.
Such combination is error-prone and discouraged:
"... and that the "goto" statement can jump between scopes, the
expectation is that usage of "goto" and cleanup helpers is never mixed
in the same function."
Actually simplify the code with a guard which allows to fix the
discouraged style by removing the goto.

The new XFS_ERRTAG_FORCE_ZERO_RANGE error tag added by commit
ea9989668081 ("xfs: error tag to force zeroing on debug kernels") fails
to account for the zoned space reservation rules and this reliably fails
xfs/131 because the zeroing operation returns -EIO.
Fix this by reserving enough space to zero the entire range, which
requires a bit of (fairly ugly) reshuffling to do the error injection
early enough to affect the space reservation.

Add support for Dosilicon DS35Q1GA (3.3V) and DS35M1GA (1.8V) SPI NAND.
These are 1Gbit (128MB) devices with:
- 2048 byte pages + 64 byte OOB
- 64 pages per block, 1024 blocks
- On-die 4-bit ECC per 512 byte sector
The 64-byte OOB area is divided into 4 segments of 16 bytes, with each
segment containing 8 bytes of user data (M2+M1) and 8 bytes of ECC
parity (R1). This provides 30 bytes of usable OOB space after reserving
2 bytes for the bad block marker.
Tested on Genexis Platinum 4410 (EcoNet EN751221) by writing known
patterns to OOB and verifying ECC parity placement in R1 regions.

This reverts commit dd26402642.
The issue George met is due to the limit of QPIC, not the issue of the
flash chip.
QPIC only supports 4 bytes ID. So the fifth byte is always 0.
If we use spi-gpio, the fifth byte can be read correctly.
