Enable SND_SOC_SPDIF in imx_v6_v7_defconfig to support SPDIF audio.
With commit d469b771afe1 ("ARM: dts: imx6: update spdif sound card node
properties"), the more generic audio-codec property is used instead of
the old spdif-controller property. Since most i.MX6 boards now use the
audio-codec property together with the linux,spdif-dit and
linux,spdif-dir compatible driver, it makes sense to enable
SND_SOC_SPDIF in the imx_v6_v7_defconfig. This will ensure compatibility
with the updated device tree.
Without this change, boards that use the audio-codec property will show
the following error message during boot when using the
imx_v6_v7_defconfig and spdif audio is not working:

When looking up a non-existent file, efivarfs returns -EINVAL if the
file does not conform to the NAME-GUID format and -ENOENT if it does.
This is caused by efivars_d_hash() returning -EINVAL if the name is not
formatted correctly. This error is returned before simple_lookup()
returns a negative dentry, and is the error value that the user sees.
Fix by removing this check. If the file does not exist, simple_lookup()
will return a negative dentry leading to -ENOENT and efivarfs_create()
already has a validity check before it creates an entry (and will
correctly return -EINVAL)

Introduces the alc2xx-fixup-headset-mic model to simplify enabling
headset microphones on ALC2XX codecs.
Many recent configurations, as well as older systems that lacked this
fix for a long time, leave headset microphones inactive by default.
This addition provides a flexible workaround using the existing
ALC2XX_FIXUP_HEADSET_MIC quirk.

CA0132 used the PCI SSID lookup helper that doesn't support the model
string matching or quirk aliasing.
Replace it with the standard HD-audio quirk helpers for supporting
those, and add the definition of the model strings for supported
quirks, too. There should be no visible change to the outside for the
working system, but the driver will parse the model option and apply
the quirk based on it from now on.

This device returns signed, 16-bit samples as stated in its datasheet
(see 8.5.2 Data Format). That is in line with the scan_type definition
for the IIO_VOLTAGE channel, but 'unsigned int' is being used to read
and push the data to userspace.
Given that the size of that type depends on the architecture (at least
2 bytes to store values up to 65535, but its actual size is often 4
bytes), use the 's16' type to provide the same structure in all cases.

The central change is in patch 4/5. It recovers a port from a very
reproducible condition where previously, it would become unable to take
any hardware TX timestamp.
Then we have patches 1/5 and 5/5 which are extra bug fixes.
Patches 2/5 and 3/5 are logical changes split out of the monolithic
patch previously submitted as v1, so that patch 4/5 is hopefully easier
to follow.

An unsupported RX filter will leave the port with TX timestamping still
applied as per the new request, rather than the old setting. When
parsing the tx_type, don't apply it just yet, but delay that until after
we've parsed the rx_filter as well (and potentially returned -ERANGE for
that).
Similarly, copy_to_user() may fail, which is a rare occurrence, but
should still be treated by unwinding what was done.

The Felix DSA driver presents unique challenges that make the simplistic
ocelot PTP TX timestamping procedure unreliable: any transmitted packet
may be lost in hardware before it ever leaves our local system.
This may happen because there is congestion on the DSA conduit, the
switch CPU port or even user port (Qdiscs like taprio may delay packets
indefinitely by design).
The technical problem is that the kernel, i.e. ocelot_port_add_txtstamp_skb(),
runs out of timestamp IDs eventually, because it never detects that
packets are lost, and keeps the IDs of the lost packets on hold
indefinitely. The manifestation of the issue once the entire timestamp
ID range becomes busy looks like this in dmesg:
mscc_felix 0000:00:00.5: port 0 delivering skb without TX timestamp
mscc_felix 0000:00:00.5: port 1 delivering skb without TX timestamp
At the surface level, we need a timeout timer so that the kernel knows a
timestamp ID is available again. But there is a deeper problem with the
implementation, which is the monotonically increasing ocelot_port->ts_id.
In the presence of packet loss, it will be impossible to detect that and
reuse one of the holes created in the range of free timestamp IDs.
What we actually need is a bitmap of 63 timestamp IDs tracking which one
is available. That is able to use up holes caused by packet loss, but
also gives us a unique opportunity to not implement an actual timer_list
for the timeout timer (very complicated in terms of locking).
We could only declare a timestamp ID stale on demand (lazily), aka when
there's no other timestamp ID available. There are pros and cons to this
approach: the implementation is much more simple than per-packet timers
would be, but most of the stale packets would be quasi-leaked - not
really leaked, but blocked in driver memory, since this algorithm sees
no reason to free them.
An improved technique would be to check for stale timestamp IDs every
time we allocate a new one. Assuming a constant flux of PTP packets,
this avoids stale packets being blocked in memory, but of course,
packets lost at the end of the flux are still blocked until the flux
resumes (nobody left to kick them out).
Since implementing per-packet timers is way too complicated, this should
be good enough.
Testing procedure:
Persistently block traffic class 5 and try to run PTP on it:

(...)
Notice that in this new usage pattern, a non-congested port should
basically use timestamp ID 0 all the time, progressing to higher numbers
only if there are unacknowledged timestamps in flight. Compare this to
the old usage, where the timestamp ID used to monotonically increase
modulo OCELOT_MAX_PTP_ID.
In terms of implementation, this simplifies the bookkeeping of the
ocelot_port :: ts_id and ptp_skbs_in_flight. Since we need to traverse
the list of two-step timestampable skbs for each new packet anyway, the
information can already be computed and does not need to be stored.
Also, ocelot_port->tx_skbs is always accessed under the switch-wide
ocelot->ts_id_lock IRQ-unsafe spinlock, so we don't need the skb queue's
lock and can use the unlocked primitives safely.
This problem was actually detected using the tc-taprio offload, and is
causing trouble in TSN scenarios, which Felix (NXP LS1028A / VSC9959)
supports but Ocelot (VSC7514) does not. Thus, I've selected the commit
to blame as the one adding initial timestamping support for the Felix
switch.

ocelot_get_txtstamp() is a threaded IRQ handler, requested explicitly as
such by both ocelot_ptp_rdy_irq_handler() and vsc9959_irq_handler().
As such, it runs with IRQs enabled, and not in hardirq context. Thus,
ocelot_port_add_txtstamp_skb() has no reason to turn off IRQs, it cannot
be preempted by ocelot_get_txtstamp(). For the same reason,
dev_kfree_skb_any_reason() will always evaluate as kfree_skb_reason() in
this calling context, so just simplify the dev_kfree_skb_any() call to
kfree_skb().
Also, ocelot_port_txtstamp_request() runs from NET_TX softirq context,
not with hardirqs enabled. Thus, ocelot_get_txtstamp() which shares the
ocelot_port->tx_skbs.lock lock with it, has no reason to disable hardirqs.
This is part of a larger rework of the TX timestamping procedure.
A logical subportion of the rework has been split into a separate
change.

This condition, theoretically impossible to trigger, is not really
handled well. By "continuing", we are skipping the write to SYS_PTP_NXT
which advances the timestamp FIFO to the next entry. So we are reading
the same FIFO entry all over again, printing stack traces and eventually
killing the kernel.
No real problem has been observed here. This is part of a larger rework
of the timestamp IRQ procedure, with this logical change split out into
a patch of its own. We will need to "goto next_ts" for other conditions
as well.

If ocelot_port_add_txtstamp_skb() fails, for example due to a full PTP
timestamp FIFO, we must undo the skb_clone_sk() call with kfree_skb().
Otherwise, the reference to the skb clone is lost.

syzkaller reported a warning in __sk_skb_reason_drop().
Commit 61b95c70f344 ("net: ip: make ip_route_input_rcu() return

Then, the cited commit started to trigger the warning with the
invalid error.
Let's fix it by returning SKB_DROP_REASON_NOT_SPECIFIED.

Commit 66600fac7a98 ("net: stmmac: TSO: Fix unbalanced DMA map/unmap
for non-paged SKB data") moved the assignment of tx_skbuff_dma[]'s
members to be later in stmmac_tso_xmit().
The buf (dma cookie) and len stored in this structure are passed to
dma_unmap_single() by stmmac_tx_clean(). The DMA API requires that
the dma cookie passed to dma_unmap_single() is the same as the value
returned from dma_map_single(). However, by moving the assignment
later, this is not the case when priv->dma_cap.addr64 > 32 as "des"
is offset by proto_hdr_len.
This causes problems such as:
dwc-eth-dwmac 2490000.ethernet eth0: Tx DMA map failed
and with DMA_API_DEBUG enabled:
DMA-API: dwc-eth-dwmac 2490000.ethernet: device driver tries to +free DMA memory it has not allocated [device address=0x000000ffffcf65c0] [size=66 bytes]
Fix this by maintaining "des" as the original DMA cookie, and use
tso_des to pass the offset DMA cookie to stmmac_tso_allocator().
Full details of the crashes can be found at:

The commit in Fixes adds a special case when only one possible scale is
available.
If several scales are available, it sets the .read_avail field of the
struct iio_info to ad9467_read_avail().
However, this field already holds this function pointer, so the code is a
no-op.
Use another struct iio_info instead to actually reflect the intent
described in the commit message. This way, the structure to use is selected
at runtime and they can be kept as const.
This is safer because modifying static structs that are shared between all
instances like this, based on the properties of a single instance, is
asking for trouble down the road.

Fix a possible race condition during driver probe in the ad7173 driver
due to using a shared static info struct. If more that one instance of
the driver is probed at the same time, some of the info could be

To fix this, make the static info struct const so that it is read-only
and make a copy of the info struct for each instance of the driver that
can be modified.

The 'scan' local struct is used to push data to user space from a
triggered buffer, but it does not set values for inactive channels, as
it only uses iio_for_each_active_channel() to assign new values.
Initialize the struct to zero before using it to avoid pushing
uninitialized information to userspace.

The 'data' array is allocated via kmalloc() and it is used to push data
to user space from a triggered buffer, but it does not set values for
inactive channels, as it only uses iio_for_each_active_channel()
to assign new values.
Use kzalloc for the memory allocation to avoid pushing uninitialized
information to userspace.

The test config contained a copy-paste error. The IIO GTS helper test
was errorneously titled as "Test IIO formatting functions" in the
menuconfig.
Change the title of the tests to reflect what is tested.
