The negation operator is incorrectly placed outside the unlikely()
macro:
if (!unlikely(iwa))
This inverts the compiler branch prediction hint, marking the NULL case
as likely instead of unlikely. The intent is to indicate that allocation
failures are rare, consistent with common kernel patterns.
Moving the negation inside unlikely():
if (unlikely(!iwa))

Since the commit c1f3f9797c1f ("can: netlink: can_changelink(): fix NULL
pointer deref of struct can_priv::do_set_mode"), the automatic restart
delay can only be set for devices that implement the restart handler struct
can_priv::do_set_mode. As it makes no sense to configure a automatic
restart for devices that doesn't support it.
However, since systemd commit 13ce5d4632e3 ("network/can: properly handle
CAN.RestartSec=0") [1], systemd-networkd correctly handles a restart delay
of "0" (i.e. the restart is disabled). Which means that a disabled restart
is always configured in the kernel.
On systems with both changes active this causes that CAN interfaces that
don't implement a restart handler cannot be brought up by systemd-networkd.
Solve this problem by allowing a delay of "0" to be configured, even if the
device does not implement a restart handler.

Coverity is unhappy because we may leak old_radio_rts_threshold. Since
this pointer is only valid in the context of the function and kfree is

Note that somehow, we were checking old_rts_threshold to free
old_radio_rts_threshold which is a bit odd.

Currently, whenever there is a need to transmit an Action frame,
the brcmfmac driver always uses the P2P vif to send the "actframe" IOVAR to
firmware. The P2P interfaces were available when wpa_supplicant is managing
the wlan interface.
However, the P2P interfaces are not created/initialized when only hostapd
is managing the wlan interface. And if hostapd receives an ANQP Query REQ
Action frame even from an un-associated STA, the brcmfmac driver tries
to use an uninitialized P2P vif pointer for sending the IOVAR to firmware.
This NULL pointer dereferencing triggers a driver crash.

Fix this, by always using the vif corresponding to the wdev on which the
Action frame Transmission request was initiated by the userspace. This way,
even if P2P vif is not available, the IOVAR is sent to firmware on AP vif
and the ANQP Query RESP Action frame is transmitted without crashing the
driver.
Move init_completion() for "send_af_done" from brcmf_p2p_create_p2pdev()
to brcmf_p2p_attach(). Because the former function would not get executed
when only hostapd is managing wlan interface, and it is not safe to do
reinit_completion() later in brcmf_p2p_tx_action_frame(), without any prior
init_completion().
And in the brcmf_p2p_tx_action_frame() function, the condition check for
P2P Presence response frame is not needed, since the wpa_supplicant is
properly sending the P2P Presense Response frame on the P2P-GO vif instead
of the P2P-Device vif.

path, which is common in max98090 and max98091 and has been defined as
DAPM suppy widget as "AHPF" in
"struct snd_soc_dapm_widget max98090_dapm_widget[]".
It is the DC-Blocking filter for the primary record path.
But the same functionality for secondary record path in the configuration
register(0x26) is DMIC2_HPF(bit2). It is not present as a DAPM supply
widget in the current code. With this patch adding it as a DAPM supply
widget. In the current code, the mics on secondary record path in
code are named as "DMIC3" and "DMIC4", so accordingly naming
DMIC2_HPF(bit2) as "DMIC34_HPF", and declaring it as a DAPM supply
widget in "struct snd_soc_dapm_widget max98091_dapm_widget[]". Also it
is specific to max98091, and should be visible or working only when
max98091 codec chip is used. Therefore, written in
"max98091_dapm_widget[]". As "AHPF" is not part
of secondary record path, replacing it with "DMIC34_HPF" in the
ALSA routes to "DMIC3" and "DMIC4" in "max98091_dapm_routes[]".

In `UVERBS_METHOD_CQ_CREATE`, umem should be released if anything goes
wrong. Currently, if `create_cq_umem` fails, umem would not be

The driver maintains a CQ table that is used to ensure that a CQ is
still valid when processing CQ related AEs. When a CQ is destroyed,
the table entry is cleared, using irdma_cq.cq_num as the index. This
field was never being set, so it was just always clearing out entry
0.
Additionally, the cq_num field size was increased to accommodate HW
supporting more than 64K CQs.

The current error handling path in bnxt_re_destroy_gsi_sqp() could lead
to a resource leak. When bnxt_qplib_destroy_qp() fails, the function
jumps to the 'fail' label and returns immediately, skipping the call
to bnxt_qplib_free_qp_res().
Continue the resource teardown even if bnxt_qplib_destroy_qp() fails,
which aligns with the driver's general error handling strategy and
prevents the potential leak.

Resolve this smatch warning:
arch/riscv/kernel/sys_hwprobe.c:50 hwprobe_arch_id() error: uninitialized symbol 'cpu_id'.
This could happen if hwprobe_arch_id() was called with a key ID of
something other than MVENDORID, MIMPID, and MARCHID. This does not
happen in the current codebase. The only caller of hwprobe_arch_id()
is a function that only passes one of those three key IDs.
For the sake of reducing static analyzer warning noise, and in the
unlikely event that hwprobe_arch_id() is someday called with some
other key ID, validate hwprobe_arch_id()'s input to ensure that
'cpu_id' is always initialized before use.

In has_thead_homogeneous_vlenb(), smatch detected that the vlenb variable
could be used while uninitialized. It appears that this could happen if
no CPUs described in DT have the "thead,vlenb" property.
Fix by initializing vlenb to 0, which will keep thead_vlenb_of set to 0
(as it was statically initialized). This in turn will cause
riscv_v_setup_vsize() to fall back to CSR probing - the desired result if
thead,vlenb isn't provided in the DT data.
While here, fix a nearby comment typo.

According to the CRB over FF-A specification [1], a TPM that implements
the ABI must comply with the TCG PTP specification. This requires support
for the Idle and Ready states.
This patch implements CRB control area requests for goIdle and
cmdReady on FF-A based TPMs.
The FF-A message used to notify the TPM of CRB updates includes a
locality parameter, which provides a hint to the TPM about which
locality modified the CRB. This patch adds a locality parameter
to __crb_go_idle() and __crb_cmd_ready() to support this.

The hwprobe vDSO data for some keys, like MISALIGNED_VECTOR_PERF,
is determined by an asynchronous kthread. This can create a race
condition where the kthread finishes after the vDSO data has
already been populated, causing userspace to read stale values.
To fix this race, a new 'ready' flag is added to the vDSO data,
initialized to 'false' during arch_initcall_sync. This flag is
checked by both the vDSO's user-space code and the riscv_hwprobe
syscall. The syscall serves as a one-time gate, using a completion
to wait for any pending probes before populating the data and
setting the flag to 'true', thus ensuring userspace reads fresh
values on its first request.

The pgprot_dmacoherent() is used when allocating memory for
non-coherent devices and by default pgprot_dmacoherent() is
same as pgprot_noncached() unless architecture overrides it.
Currently, there is no pgprot_dmacoherent() definition for
RISC-V hence non-coherent device memory is being mapped as
IO thereby making CPU access to such memory slow.
Define pgprot_dmacoherent() to be same as pgprot_writecombine()
for RISC-V so that CPU access non-coherent device memory as
NOCACHE which is better than accessing it as IO.
