There is no need to pass a genpd struct to pm_genpd_remove_device(), as we
already have the information about the PM domain (genpd) through the device
structure.
Additionally, we don't allow to remove a PM domain from a device, other
than the one it may have assigned to it, so really it does not make sense
to have a separate in-param for it.
For these reason, drop it and update the current only call to
pm_genpd_remove_device() from amdgpu_acp.

In Certain QCOM SoCs like apq8096 and msm8996 that have KRYO processors,
the CPU frequency subset and voltage value of each OPP varies
based on the silicon variant in use. Qualcomm Process Voltage Scaling Tables
defines the voltage and frequency value based on the msm-id in SMEM
and speedbin blown in the efuse combination.
The qcom-cpufreq-kryo driver reads the msm-id and efuse value from the SoC
to provide the OPP framework with required information.
This is used to determine the voltage and frequency value for each OPP of
operating-points-v2 table when it is parsed by the OPP framework.

This can contain more than one phandle for power domain

then the same OPP table will be used for all power domains

Tests showed, that the zcrypt device driver produces memory
leaks when a valid CCA or EP11 CPRB can't get delivered or has
a failure during processing within the zcrypt device driver.
This happens when a invalid domain or adapter number is used
or the lower level software or hardware layers produce any
kind of failure during processing of the request.
Only CPRBs send to CCA or EP11 cards can produce this memory
leak. The accelerator and the CPRBs processed by this type
of crypto card is not affected.
The two fields message and private within the ap_message struct
are allocated with pulling the function code for the CPRB but
only freed when processing of the CPRB succeeds. So for example
an invalid domain or adapter field causes the processing to
fail, leaving these two memory areas allocated forever.

This avoids the init_cpufreq_transition_notifier_list() initcall. Its

If the policy limits are updated via cpufreq_update_policy() and
subsequently via sysfs, the limits stored in user_policy may be
set incorrectly.
For example, if both min and max are set via sysfs to the maximum
available frequency, user_policy.min and user_policy.max will also
be the maximum. If a policy notifier triggered by
cpufreq_update_policy() lowers both the min and the max at this
point, that change is not reflected by the user_policy limits, so
if the max is updated again via sysfs to the same lower value,
then user_policy.max will be lower than user_policy.min which
shouldn't happen. In particular, if one of the policy CPUs is
then taken offline and back online, cpufreq_set_policy() will
fail for it due to a failing limits check.
To prevent that from happening, initialize the min and max fields
of the new_policy object to the ones stored in user_policy that
were previously set via sysfs.

Initially in this code, the race didn't matter since it didn't
do anything. Latest with the commit I marked this as fixing it
started to matter as something got done here that needed other
data that got freed as soon as the queue notification wait was
returning.
In the scenario we saw, apparently the IWL_MVM_RXQ_NOTIF_DEL_BA
event was sent to all queues, but processing the last event we
returned from iwl_mvm_sync_rx_queues_internal() and then from
iwl_mvm_free_reorder() and continued some processing before
wl_mvm_del_ba() was even invoked on the other CPU. Thus, when
the latter finally ran, it found that mvm->baid_map[baid] was
no longer valid.
Correct the race by moving the counter decrement and wake_up()
to be done only after all the per-event processing completed.
Note that in the commit I marked as being fixed the wake_up()
didn't exist yet (and the code was otherwise problematic) but
this particular problem already existed in a way.

When we receive a RMI4 report, we should not unconditionally send an

This fixes a situation where we might receive X in a report and the rest
in a subsequent one. And this messes up user space.

According to [1] and also seemingly agreed by [2], the Scan Time usage
(0x0D 0x56) is a report level usage, not a contact level usage.
However, the hid-multitouch driver currently includes HID_DG_SCANTIME
when calculating `td->last_slot_field', which may lead to
mt_complete_slot() being prematurely called in certain cases (e.g. when
each touch input report includes more than one contact and the Scan Time
usage appears before any contact logical collection).
This patch fixes the issue by skipping mt_store_field() on
HID_DG_SCANTIME, similar to how HID_DG_CONTACTCOUNT and
HID_DG_CONTACTMAX are handled.

hid_have_special_driver[]
Delcom offers different types of products sharing the same USB VID/PID
as the Visual Signal Indicator. Other products need to be handled by
HID Generic what's not possible currently because USB VID/PID are
listed in hid_have_special_driver[].
After e04a0442d33b ("HID: core: remove the absolute need of
hid_have_special_driver[]") we can now remove the Delcom entry.
If a Visual Signal Indicator device is plugged-in, HID core
will start a reprobe if hid-led driver is available.
If another device with same USB VID/PID is plugged-in, then hid-led
can be blacklisted and HID Generic handles the device.
Thanks to Delcom for providing test devices.

Our hardware has a limited amount of buffer descriptors
for each Tx packet. Because of that, there is a short
piece of code that makes sure that that we don't push too
many subframes in an A-MSDU because of subframes needs 2
buffer descriptors. This code also takes into account the
number of fragment of the skb since we also need a buffer
descriptor for each fragment in the skb.
This piece of code though didn't check that the resulting
number of subframes wasn't 0.
A user reported that using NFS client, he could get skbs
that are so fragmented that the code mentioned above
returned 0 for the number of subframes making

In some cases we may get from FW errored frames with

This may happen in unsecured aggregation flow, where
the first packet had a CRC error in the WEP bit, which
was followed by a failure to decrypt and was dropped.
The next frames in the aggregation "inherit" the bad metadata
of the first packet.
Make sure to drop such frames since RADA and other offloads
will not operate correctly which may have unexpected results.
In case of AP it also causes to TX AMSDU frames to the peers,

From SDM845, the Q6SS reset sequence on software side has been
simplified with the introduction of boot FSM which assists in
bringing the Q6 out of reset.
SDM845 brings a new reset signal ALT_RESET which is a part of
the MSS subsystem hence requires reset clks to be enabled before
assert/deassert. Use the SoC specific reset helper function to
add support for ALT_RESET in SDM845.
