The function performs a check on its input parameters, however, the
hdev parameter is used before the check.
Initialize the stack variables after checking the input parameters to
avoid a possible NULL pointer dereference.

If bInterval is 1, then p_interval is 8000 and p_interval_mil is 8E9,
which is too big for a 32-bit value. While the storage is indeed
64-bit, this value is used as the divisor in do_div() which will
truncate it into a uint32_t leading to incorrect calculated values.
Switch back to keeping the base value in struct snd_uac_chip which fits
easily into an int, meaning that the division can be done in two steps
with the divisor fitting safely into a uint32_t on both steps.

DWC2 may be paired with a full-speed PHY which is not capable of
high-speed operation. Report this correctly to the gadget core by
setting max_speed from the core parameters.
Prior to commit 5324bad66f09f ("usb: dwc2: gadget: implement
udc_set_speed()") this didn't cause the hardware to be configured
incorrectly, although the speed may have been reported incorrectly. But
after that commit params.speed is updated based on a value passed in by
the gadget core which may set it to a faster speed than is supported by
the hardware. Initialising the max_speed parameter ensures the speed
passed to dwc2_gadget_set_speed() will be one supported by the hardware.

The RPMh regulator driver is much newer and gets more attention, which in
consequence makes it do a few things better. Update qcom_smd-regulator's
probe function to mimic what rpmh-regulator does to address a couple of
issues:
- Probe defer now works correctly, before it used to, well,
kinda just die.. This fixes reliable probing on (at least) PM8994,
because Linux apparently cannot deal with supply map dependencies yet..
- Regulator data is now matched more sanely: regulator data is matched
against each individual regulator node name and throwing an -EINVAL if
data is missing, instead of just assuming everything is fine and
iterating over all subsequent array members.
- status = "disabled" will now work for disabling individual regulators in
DT. Previously it didn't seem to do much if anything at all.

but instead of using one of the JD pins of the codec, an external GPIO

AMCR0F28 ACPI dev
Some X86 tablets, which ship with Android as factory installed OS,
specify codec IRQs/GPIOS in a special Android AMCR0F28 ACPI device.
Add support for retrieving the codec IRQ from this ACPI device instead
of from the 10EC5640 device describing the codec itself and enable this

Commit 2b9c8d2b3c89 ("ASoC: rt5640: Add the HDA header support") adds
re-queuing of the jack_work on resume when rt5640->jd_src != 0.
But the jack_work will unconditionally deref rt5640->jack and that might
be NULL. E.g. the sound/soc/intel/boards/bytcr_rt5640.c machine driver
call snd_soc_component_set_jack(codec, NULL, NULL) from pre_suspend to
disable the IRQ to avoid spurious wakeups, so when rt5640_resume()
runs rt5640->jack will be NULL in this case.
Make the queueing of the work conditional on rt5640->jack instead of
on rt5640->jd_src to fix this.

SMC connections might fail to be registered in a link group due to
unable to find a usable link during its creation. As a result,
smc_conn_create() will return a failure and most resources related
to the connection won't be applied or initialized, such as
conn->abort_work or conn->lnk.
If smc_conn_free() is invoked later, it will try to access the
uninitialized resources related to the connection, thus causing
a warning or crash.
This patch tries to fix this by resetting conn->lgr to NULL if an
abnormal exit occurs in smc_lgr_register_conn(), thus avoiding the
access to uninitialized resources in smc_conn_free().
Meanwhile, the new created link group should be terminated if smc
connections can't be registered in it. So smc_lgr_cleanup_early() is
modified to take care of link group only and invoked to terminate
unusable link group by smc_conn_create(). The call to smc_conn_free()
is moved out from smc_lgr_cleanup_early() to smc_conn_abort().

Laurent reported that they have seen a significant amount of TCP retransmissions
at high throughput from applications residing in network namespaces talking to
the outside world via veths. The drops were seen on the qdisc layer (fq_codel,
as per systemd default) of the phys device such as ena or virtio_net due to all
traffic hitting a _single_ TX queue _despite_ multi-queue device. (Note that the
setup was _not_ using XDP on veths as the issue is generic.)
More specifically, after edbea9220251 ("veth: Store queue_mapping independently
of XDP prog presence") which made it all the way back to v4.19.184+,
skb_record_rx_queue() would set skb->queue_mapping to 1 (given 1 RX and 1 TX
queue by default for veths) instead of leaving at 0.
This is eventually retained and callbacks like ena_select_queue() will also pick
single queue via netdev_core_pick_tx()'s ndo_select_queue() once all the traffic
is forwarded to that device via upper stack or other means. Similarly, for others
not implementing ndo_select_queue() if XPS is disabled, netdev_pick_tx() might
call into the skb_tx_hash() and check for prior skb_rx_queue_recorded() as well.
In general, it is a _bad_ idea for virtual devices like veth to mess around with
queue selection [by default]. Given dev->real_num_tx_queues is by default 1,
the skb->queue_mapping was left untouched, and so prior to edbea9220251 the
netdev_core_pick_tx() could do its job upon __dev_queue_xmit() on the phys device.
Unbreak this and restore prior behavior by removing the skb_record_rx_queue()
from veth_xmit() altogether.
If the veth peer has an XDP program attached, then it would return the first RX
queue index in xdp_md->rx_queue_index (unless configured in non-default manner).
However, this is still better than breaking the generic case.

In the kernel, all names related to the chip BCM2835 are always named
bcm2835_*. To avoid confusion, and to make things more consistent,
rename functions using bm2835_* to bcm2835_*.
While at it, some realignments were made to improve readability.

bm2835_mmal_v4l2_ctrl
In the kernel, all names related to the chip BCM2835 are always named
bcm2835_*. To avoid confusion, and to make things more consistent,
rename the structures bm2835_mmal_dev and bm2835_mmal_v4l2_ctrl
accordingly.
While at it, one realignment was made to improve readability.

There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field. Move the ibmveth sysfs code to use default_groups
field which has been the preferred way since aa30f47cf666 ("kobject: Add
support for default attribute groups to kobj_type") so that we can soon
get rid of the obsolete default_attrs field.

As the possible alloc failure of devm_kcalloc(), it could return null
pointer.
Therefore, 'strings' should be checked and return NULL if alloc fails to
prevent the dereference of the NULL pointer.
Also, the caller should also deal with the return value of the
gb_generate_enum_strings() and return -ENOMEM if returns NULL.
Moreover, because the memory allocated with devm_kzalloc() will be
freed automatically when the last reference to the device is dropped,
the 'gbe' in gbaudio_tplg_create_enum_kctl() and
gbaudio_tplg_create_enum_ctl() do not need to free manually.
But the 'control' in gbaudio_tplg_create_widget() and
gbaudio_tplg_process_kcontrols() has a specially error handle to
cleanup.
So it should be better to cleanup 'control' when fails.

This happened because we would overrun the i2c->msgs array on the final
interrupt for the I2C STOP. This didn't happen if the last message was a
read because there is no interrupt in that case. Ensure that we only
access the current message if we are not processing a I2C STOP
condition.

The default_attrs array of attributes for the edd sysfs entries is
totally empty for some reason, and a list of attributes is added later
after the object is created (which should be fixed up later as it's
racy). Because this pointer is never used, and is empty, and we are
trying to remove all default_attrs usages, just delete it.
