Previously we were filtering out only upper unsupported sampling rates.
This patch adds filtering of the lower unsupported sampling rates. As a
result there is 1:1 mapping between altsetting and supported rates.
The issue was found on a Scarlett 3rd Gen card (see linked bug), but the
same filtering is likely needed for the Scarlett 1st and 2nd Gen as well
as the older Clarett cards which lacks Valid Alternate Setting Control.
Patch was not tested on a real hardware.

The mute led on this laptop is using ALC245 but requires a quirk to work

ASoC: Fixes for v6.16
A small collection of fixes, the main one being a fix for resume from
hibernation on AMD systems, plus a few new quirk entries for AMD
systems.
The find_substream() call may return NULL, but the error path
dereferenced 'subs' unconditionally via dev_err(&subs->dev->dev, ...),
causing a NULL pointer dereference when subs is NULL.
Fix by switching to &uadev[idx].udev->dev which is always valid
in this context.

ASUS UM5606* models use the quirk to set up the bass speakers, but it
missed the mic-mute LED configuration. Other similar models have the
AMD ACP dmic, and the mic-mute is set up for that, but those models
don't have AMD ACP but rather built-in mics of Realtek codec, hence
the Realtek driver should set it up, instead.

In snd_usb_get_audioformat_uac3(), the length value returned from
snd_usb_ctl_msg() is used directly for memory allocation without
validation. This length is controlled by the USB device.
The allocated buffer is cast to a uac3_cluster_header_descriptor
and its fields are accessed without verifying that the buffer
is large enough. If the device returns a smaller than expected
length, this leads to an out-of-bounds read.
Add a length check to ensure the buffer is large enough for
uac3_cluster_header_descriptor.

During the hibernate entry sequence, ACP registers will be reset to
default values and acp ip will be completely powered off including acp
SoundWire pads. During resume sequence, if acp SoundWire pad keeper enable
register is not restored along with pad pulldown control register value,
then SoundWire manager links won't be powered on correctly results in
peripheral register access failures and completely audio function is
broken.
Add code to store the acp SoundWire pad keeper enable register and acp pad
pulldown ctrl register values before entering into suspend state and
restore the register values during resume sequence based on condition check
for acp SoundWire pad keeper enable register for ACP6.3, ACP7.0 & ACP7.1

If spacemit_i2c_xfer_msg() times out waiting for a message transfer to
complete, or if the hardware reports an error, it returns a negative
error code (-ETIMEDOUT, -EAGAIN, -ENXIO. or -EIO).
The sole caller of spacemit_i2c_xfer_msg() is spacemit_i2c_xfer(),
which is the i2c_algorithm->xfer callback function. It currently
does not save the value returned by spacemit_i2c_xfer_msg().
The result is that transfer errors go unreported, and a caller
has no indication anything is wrong.
When this code was out for review, the return value *was* checked
in early versions. But for some reason, that assignment got dropped
between versions 5 and 6 of the series, perhaps related to reworking
the code to merge spacemit_i2c_xfer_core() into spacemit_i2c_xfer().
Simply assigning the value returned to "ret" fixes the problem.

after fabc4ed200f9, server_unresponsive add a condition to check whether client
need to reconnect depending on server->lstrp. When client failed to reconnect
for some time and abort connection, server->lstrp is updated for the last time.
In the following scene, server->lstrp is too old. This cause next command
failure in re-negotiation rather than waiting for re-negotiation done.
1. mount -t cifs -o username=Everyone,echo_internal=10 //$server_ip/export /mnt
2. ssh $server_ip "echo b > /proc/sysrq-trigger &"
3. ls /mnt
4. sleep 21s
5. ssh $server_ip "service firewalld stop"
6. ls # return EHOSTDOWN
If the interval between 5 and 6 is too small, 6 may trigger sending negotiation
request. Before backgrounding cifsd thread try to receive negotiation response
from server in cifs_readv_from_socket, server_unresponsive may trigger
cifs_reconnect which cause 6 to be failed:
ls thread
----------------
smb2_negotiate
server->tcpStatus = CifsInNegotiate
compound_send_recv
wait_for_compound_request
cifsd thread
----------------
cifs_readv_from_socket
server_unresponsive
server->tcpStatus == CifsInNegotiate && jiffies > server->lstrp + 20s
cifs_reconnect
cifs_abort_connection: mid_state = MID_RETRY_NEEDED
ls thread
----------------
cifs_sync_mid_result return EAGAIN
smb2_negotiate return EHOSTDOWN
Though server->lstrp means last server response time, it is updated in
cifs_abort_connection and cifs_get_tcp_session. We can also update server->lstrp
before switching into CifsInNegotiate state to avoid failure in 6.

"The main fix that really needs to get in is the revert of the patch
adding the new mtd_master class, because it entirely fails the
partitioning if a specific Kconfig option is set. We need to think how
to handle that differently, so let's revert it as we need to get back
to the pen and paper situation again.
Otherwise the definition of some Winbond SPI NAND chips are receiving
some fixes (geometry and maximum frequency, mostly).
And finally a small memory leak gets also fixed"

ath79_misc_irq_init() was defined but unused since commit 51fa4f8912
("MIPS: ath79: drop legacy IRQ code"), so it's time to drop it.
The build also warns about a missing prototype of get_c0_perfcount_int().
Remove the stale leftover function and add the missing include.

Currently the call_rcu() API does not check whether a callback
pointer is NULL. If NULL is passed, rcu_core() will try to invoke
it, resulting in NULL pointer dereference and a kernel crash.
To prevent this and improve debuggability, this patch adds a check
for NULL and emits a kernel stack trace to help identify a faulty
caller.

Exit to userspace for TDG.VP.VMCALL<GetTdVmCallInfo> via KVM_EXIT_TDX,
to allow userspace to provide information about the support of
TDVMCALLs when r12 is 1 for the TDVMCALLs beyond the GHCI base API.
GHCI spec defines the GHCI base TDVMCALLs: <GetTdVmCallInfo>, <MapGPA>,
<ReportFatalError>, <Instruction.CPUID>, <#VE.RequestMMIO>,
<Instruction.HLT>, <Instruction.IO>, <Instruction.RDMSR> and
<Instruction.WRMSR>. They must be supported by VMM to support TDX guests.
For GetTdVmCallInfo
- When leaf (r12) to enumerate TDVMCALL functionality is set to 0,
successful execution indicates all GHCI base TDVMCALLs listed above are
supported.
Update the KVM TDX document with the set of the GHCI base APIs.
- When leaf (r12) to enumerate TDVMCALL functionality is set to 1, it
indicates the TDX guest is querying the supported TDVMCALLs beyond
the GHCI base TDVMCALLs.
Exit to userspace to let userspace set the TDVMCALL sub-function bit(s)
accordingly to the leaf outputs. KVM could set the TDVMCALL bit(s)
supported by itself when the TDVMCALLs don't need support from userspace
after returning from userspace and before entering guest. Currently, no
such TDVMCALLs implemented, KVM just sets the values returned from
userspace.

Handle TDVMCALL for GetQuote to generate a TD-Quote.
GetQuote is a doorbell-like interface used by TDX guests to request VMM
to generate a TD-Quote signed by a service hosting TD-Quoting Enclave
operating on the host. A TDX guest passes a TD Report (TDREPORT_STRUCT) in
a shared-memory area as parameter. Host VMM can access it and queue the
operation for a service hosting TD-Quoting enclave. When completed, the
Quote is returned via the same shared-memory area.
KVM only checks the GPA from the TDX guest has the shared-bit set and drops
the shared-bit before exiting to userspace to avoid bleeding the shared-bit
into KVM's exit ABI. KVM forwards the request to userspace VMM (e.g. QEMU)
and userspace VMM queues the operation asynchronously. KVM sets the return
code according to the 'ret' field set by userspace to notify the TDX guest
whether the request has been queued successfully or not. When the request
has been queued successfully, the TDX guest can poll the status field in
the shared-memory area to check whether the Quote generation is completed
or not. When completed, the generated Quote is returned via the same
buffer.
Add KVM_EXIT_TDX as a new exit reason to userspace. Userspace is
required to handle the KVM exit reason as the initial support for TDX,
by reentering KVM to ensure that the TDVMCALL is complete. While at it,
add a note that KVM_EXIT_HYPERCALL also requires reentry with KVM_RUN.
