Like other Asus Vivobooks, the Asus Vivobook Go E1404GAB has a DSDT
that describes IRQ 1 as ActiveLow, while the kernel overrides to Edge_High.
This override prevents the internal keyboard from working.
Fix the problem by adding this laptop to the table that prevents the kernel
from overriding the IRQ.

When removing a resource from vmci_resource_table in
vmci_resource_remove(), the search is performed using the resource
handle by comparing context and resource fields.
It is possible though to create two resources with different types
but same handle (same context and resource fields).
When trying to remove one of the resources, vmci_resource_remove()
may not remove the intended one, but the object will still be freed
as in the case of the datagram type in vmci_datagram_destroy_handle().
vmci_resource_table will still hold a pointer to this freed resource
leading to a use-after-free vulnerability.

Rescind offer handling relies on rescind callbacks for some of the
resources cleanup, if they are registered. It does not unregister
vmbus device for the primary channel closure, when callback is
registered. Without it, next onoffer does not come, rescind flag
remains set and device goes to unusable state.
Add logic to unregister vmbus for the primary channel in rescind callback
to ensure channel removal and relid release, and to ensure that next
onoffer can be received and handled properly.

Binder objects are processed and copied individually into the target
buffer during transactions. Any raw data in-between these objects is
copied as well. However, this raw data copy lacks an out-of-bounds
check. If the raw data exceeds the data section size then the copy
overwrites the offsets section. This eventually triggers an error that
attempts to unwind the processed objects. However, at this point the
offsets used to index these objects are now corrupted.
Unwinding with corrupted offsets can result in decrements of arbitrary
nodes and lead to their premature release. Other users of such nodes are
left with a dangling pointer triggering a use-after-free. This issue is
made evident by the following KASAN report (trimmed):

IIO: 1st set of fixes for 6.11
The usual mixed bag of new issues and ancient ones.
The fact so many are ADI is probably due to an uptick in upstreaming
effort from Analog + Baylibre meaning existing code is getting more eyes
on it. Hence it's a good sign not a reflection of inherent high bug
incidence!
Core and helper related
-----------------------
in kernel interfaces
- Fix missing application of scale to the integer part of
IIO_INT_PLUS_XXX value pairs when using the
iio_convert_raw_to_processed*() helper.
buffer-dmaengine
- Make sure to release DMA channel in error path.
Driver related
--------------

- Check irq-flags for the correct irq if multiple are provided.
adi,ad7124
- Wait after reset before reading the chip ID register.
- Compare only the relevant field when looking for an existing
config to reuse for a new channel.
- Fix an off by one in which channel config is being filled from
firmware.
adi,ad7173
- Fix missing vendor prefix in compatible strings.
- Fix wrong info for GPIO related bit positions for ad4114,ad4115 and ad4116.
adi,ad7606
- Drop incorrect check on frstdata when in serial mode, it only applies to
parallel mode.
adi,ad9834
- Check userspace input for frequency parameter to avoid div by zero.
invensense,mpu6050
- Avoid reading interrupt status on some older chips as it seems there
is a hardware problem that surfaces as a result of adding wake on
motion support to the driver (which these chips don't support).
ti,ads1119
- Fix incorrect IRQ flag (new driver so no firmware compatibility regression
issues with fixing this now).

When a channel ctx is assigned to a link, we set the
LINK_CONTEXT_MODIFY_RATES_INFO to indicate that the rate fields are now
valid. But then we always take the rates of 2.4 GHz regardless of actual
used band.
This is because we are getting the band from bss_conf->chanctx_conf, but
this is assigned only after drv_assign_vif_chanctx returns, so we take
the bands of 2.4 GHz.
Fix it by taking the band from the iwl_mvm_link_info::phy_ctxt instead,
as this has already assigned in this point.

When we de-activate a link because it started a CSA with mode=1, we want
to tell the firmware it can no longer transmit any frame for that link.
The firmware will do that on its own if the CSA indication (beacon /
action frame) was received on that same link, but with MLO, things got
more complex and the firmware can't track cross link CSA.
Tell the firmware if we de-activate a link because of CSA with mode=1 to
prevent it from transmitting, even if it is only an NDP PM=1 frame that
is part of the de-activation flow.

The channel number is at the same position across all versions
of the channel description struct, so move it out of the union
that versions it. Also add __packed annotations to all of the
sub-structs and the union so it's packed correctly, and fully
document the structure.

Ability to handle maximum FCoE frames of 2158 bytes can never be changed
and thus more of an attribute, not a toggleable feature.
Move it from netdev_features_t to "cold" priv flags (bitfield bool) and
free yet another feature bit.

Make dev->priv_flags `u32` back and define bits higher than 31 as
bitfield booleans as per Jakub's suggestion. This simplifies code
which accesses these bits with no optimization loss (testb both
before/after), allows to not extend &netdev_priv_flags each time,
but also scales better as bits > 63 in the future would only add
a new u64 to the structure with no complications, comparing to
that extending ::priv_flags would require converting it to a bitmap.
Note that I picked `unsigned long :1` to not lose any potential
optimizations comparing to `bool :1` etc.

The following XDP_DROP test from [1] stalls the interface after
250 packets.
~# xdb-bench drop -m native eth0
This is because new RX requests are never queued. Fix that.

This commit introduces implementations of three functions:
.port_fdb_dump
.port_fdb_add
.port_fdb_del
The FDB database organization is the same as in other old Vitesse chips:
It has 2048 rows and 4 columns (buckets). The row index is calculated by
the hash function 'vsc73xx_calc_hash' and the FDB entry must be placed
exactly into row[hash]. The chip selects the bucket number by itself.

On HDMI connectors which use drm_bridge_connector and DRM_BRIDGE_OP_HDMI
IGT chokes on the max_bpc property in several kms_properties tests due
to the drm_bridge_connector failing to reset HDMI-related
properties.
Call __drm_atomic_helper_connector_hdmi_reset() if the
drm_bridge_connector has bridge_hdmi.
It is impossible to call this function from HDMI bridges, none of the
bridge callbacks correspond to the drm_connector_funcs::reset().

Kconfig symbols should not declare dependency on DRM_DISPLAY_HELPER.
Move all parts of DRM_DISPLAY_HELPER to an if DRM_DISPLAY_HELPER block.
It is not possible to make those symbols select DRM_DISPLAY_HELPER
because of the link issues when a part of the helper is selected to be
built-in, while other part is selected to be as module. In such a case
the modular part doesn't get built at all, leading to undefined symbols.
The only viable alternative is to split drm_display_helper.ko into
several small modules, each of them having their own dependencies.

The Partner PD Revision field in GET_CONNECTOR_CAPABILITY
data structure was introduced in UCSI v2.1. In
ucsi_check_connector_capability() the version was assumed to
be 2.0, and in ucsi_register_partner() the field is accessed
completely unconditionally.
Fixing the version in ucsi_check_connector_capability(), and
replacing the unconditional pd_revision assignment with a
direct call to ucsi_check_connector_capability() in
ucsi_register_port(). After this the revision is also
checked only if there is a PD contract.

This fix addresses STAR 9001285599, which only affects DWC_usb3 version
3.20a. The timer value for PM_LC_TIMER in DWC_usb3 3.20a for the Link
ECN changes is incorrect. If the PM TIMER ECN is enabled via GUCTL2[19],
the link compliance test (TD7.21) may fail. If the ECN is not enabled
(GUCTL2[19] = 0), the controller will use the old timer value (5us),
which is still acceptable for the link compliance test. Therefore, clear
GUCTL2[19] to pass the USB link compliance test: TD 7.21.

When operating in High-Speed, it is observed that DSTS[USBLNKST] doesn't
update link state immediately after receiving the wakeup interrupt. Since
wakeup event handler calls the resume callbacks, there is a chance that
function drivers can perform an ep queue, which in turn tries to perform
remote wakeup from send_gadget_ep_cmd(STARTXFER). This happens because
DSTS[[21:18] wasn't updated to U0 yet, it's observed that the latency of
DSTS can be in order of milli-seconds. Hence avoid calling gadget_wakeup
during startxfer to prevent unnecessarily issuing remote wakeup to host.
