87be7b189b Bluetooth: Fix usage of __hci_cmd_sync_status
__hci_cmd_sync_status shall only be used if hci_req_sync_lock is _not_
required which is not the case of hci_dev_cmd so it needs to use
hci_cmd_sync_status which uses hci_req_sync_lock internally.

We unnecessarily fallthrough the case for QCA6390 when initializing the
device and hit the condition where - due to the lack of the enable-gpio
- we disable power management despite using the power sequencer. We don't
need to look for clocks on this model so it makes more sense to just
register the hci device and break the switch.

2f38cf730c ALSA: usb: Fix UBSAN warning in parse_audio_unit()
A malformed USB descriptor may pass the lengthy mixer description with
a lot of channels, and this may overflow the 32bit integer shift
size, as caught by syzbot UBSAN test.  Although this won't cause any

This patch introduces a sanity check of the number of channels to bail
out the parsing when too many channels are found.

c49379dcda Merge branch 'net-dsa-vsc73xx-implement-vlan-operations'
Pawel Dembicki says:

====================
net: dsa: vsc73xx: Implement VLAN operations

This patch series is a result of splitting a larger patch series [0],
where some parts was merged before.

The first patch implements port state configuration, which is required
for bridge functionality. STP frames are not forwarded at this moment.
BPDU frames are only forwarded from/to the PI/SI interface.
For more information, see chapter 2.7.1 (CPU Forwarding) in the
datasheet.

Patches 2, 7-9 and 11 provide a basic implementation of tag_8021q
functionality with QinQ support, without VLAN filtering in
the bridge and simple VLAN awareness in VLAN filtering mode.

Patches 3-6 came from Vladimir Oltean. They prepare for making
tag8021q more common. VSC73XX uses very similar tag recognition,
and some code from tag_sja1105 could be moved to tag_8021q for
common use.

Patch 10 is preparation for use tag_8021q bridge functions as generic
implementation of the 'ds->ops->port_bridge_*()'.

Patch 12 is required to avoid problem with learning on standalone ports.

This patch implements .port_pre_bridge_flags() and .port_bridge_flags(),
which are required for properly treating the BR_LEARNING flag. Also,
.port_stp_state_set() is tweaked and now disables learning for standalone
ports.

Disabling learning for standalone ports is required to avoid situations
where one port sees traffic originating from another, which could cause
packet drops.

The vsc73xx requires minimal operations and ithe generic
dsa_tag_8021q_bridge_* API is sufficient.
The forwarding matrix is managed by vsc73xx_port_stp_state_set() ->
vsc73xx_refresh_fwd_map()i routine, which is called immediately after
.port_bridge_join() and .port_bridge_leave().

The 'dsa_tag_8021q_bridge_join' could be used as a generic implementation

to synchronize their arguments.

This patch also moves the 'tx_fwd_offload' flag configuration line into
'dsa_tag_8021q_bridge_join' body. Currently, every (sja1105) driver sets
it, and the future vsc73xx implementation will also need it for
simplification.

e3386ec4ec net: dsa: vsc73xx: Implement the tag_8021q VLAN operations
This patch is a simple implementation of 802.1q tagging in the vsc73xx
driver. Currently, devices with DSA_TAG_PROTO_NONE are not functional.
The VSC73XX family doesn't provide any tag support for external Ethernet
ports.

The only option available is VLAN-based tagging, which requires constant
hardware VLAN filtering. While the VSC73XX family supports provider
bridging, it only supports QinQ without full implementation of 802.1AD.
This means it only allows the doubled 0x8100 TPID.

In the simple port mode, QinQ is enabled to preserve forwarding of
VLAN-tagged frames.

(non-tag_8021q) source, we can now unify the call sequence between
sja1105_rcv() and sja1110_rcv().

This is a preparatory change for creating a higher-level wrapper for the
entire sequence which will live in tag_8021q.

0064b863ab net: dsa: tag_sja1105: absorb entire sja1105_vlan_rcv() into dsa_8021q_rcv()
tag_sja1105 has a wrapper over dsa_8021q_rcv(): sja1105_vlan_rcv(),
which determines whether the packet came from a bridge with
vlan_filtering=1 (the case resolved via
dsa_find_designated_bridge_port_by_vid()), or if it contains a tag_8021q
header.

Looking at a new tagger implementation for vsc73xx, based also on
tag_8021q, it is becoming clear that the logic is needed there as well.
So instead of forcing each tagger to wrap around dsa_8021q_rcv(), let's
merge the logic into the core.

dcfe767378 net: dsa: tag_sja1105: absorb logic for not overwriting precise info into dsa_8021q_rcv()
In both sja1105_rcv() and sja1110_rcv(), we may have precise source port
information coming from parallel hardware mechanisms, in addition to the
tag_8021q header.

Only sja1105_rcv() has extra logic to not overwrite that precise info
with what's present in the VLAN tag. This is because sja1110_rcv() gets
by, by having a reversed set of checks when assigning skb->dev. When the
source port is imprecise (vbid >=1), source_port and switch_id will be
set to zeroes by dsa_8021q_rcv(), which might be problematic. But by
checking for vbid >= 1 first, sja1110_rcv() fends that off.

We would like to make more code common between sja1105_rcv() and
sja1110_rcv(), and for that, we need to make sure that sja1110_rcv()
also goes through the precise source port preservation logic.

f0eb154c39 irqchip/gic-v4: Substitute vmovp_lock for a per-VM lock
vmovp_lock is abused in a number of cases to serialise updates
to vlpi_count[] and deal with map/unmap of a VM to ITSs.

Instead, provide a per-VM lock and revisit the use of vlpi_count[]
so that it is always wrapped in this per-VM vmapp_lock.

This reduces the potential contention on a concurrent VMOVP command,
and paves the way for subsequent VPE locking that holding vmovp_lock
actively prevents due to the lock ordering.

There are currently two paths to set the initial affinity of a VPE:

 - at activation time on GICv4 without the stupid VMOVP list, and

The latter location may end-up modifying the affinity of VPE that is
currently running, making the results unpredictible.

Instead, unify the two paths, making sure to set the initial affinity only
at activation time.

Fix this by building a new module (icssg.o) for all the common objects.
Both the driver can then depend on this common module.

Some APIs being exported have emac_ as the prefix which may result into
confusion with other existing APIs with emac_ prefix, to avoid
confusion, rename the APIs being exported with emac_ to icssg_ prefix.

This also fixes below error seen when both drivers are built.

is a uAPI change with a differently ordered enum. This may become a bigger
problem in next cycles when iommu_hwpt_invalidate_data_type and other
per-driver enums have patches flowing through different trees.

So lets start including constants for all the uAPI enums to make this
safer.
