commit 2ca34b5087 upstream.
Remove erroneous subtraction of 4 from the total FIFO depth read from
device tree. The stored depth is for checking against total capacity,
not initial vacancy. This prevented writes near the FIFO's full size.
The check performed just before data transfer, which uses live reads of
the TDFV register to determine current vacancy, correctly handles the
initial Depth - 4 hardware state and subsequent FIFO fullness.

commit c6e8d85faf upstream.
The axis-fifo driver performs a full hardware reset (via
reset_ip_core()) in several error paths within the read and write
functions. This reset flushes both TX and RX FIFOs and resets the
AXI-Stream links.
Allow the user to handle the error without causing hardware disruption
or data loss in other FIFO paths.

commit 2e92295627 upstream.
The mode setting logic in ad7816_store_mode was reversed due to
incorrect handling of the strcmp return value. strcmp returns 0 on
match, so the `if (strcmp(buf, "full"))` block executed when the
input was not "full".
This resulted in "full" setting the mode to AD7816_PD (power-down) and
other inputs setting it to AD7816_FULL.
Fix this by checking it against 0 to correctly check for "full" and
"power-down", mapping them to AD7816_FULL and AD7816_PD respectively.

commit 4636e859eb upstream.
User Perspective:
When a user sets the phase value, the ad9832_write_phase() is called.
The phase register has a 12-bit resolution, so the valid range is 0 to
4095. If the phase offset value of 4096 is input, it effectively exactly
equals 0 in the lower 12 bits, meaning no offset.
Reasons for the Change:
1) Original Condition (phase > BIT(AD9832_PHASE_BITS)):
This condition allows a phase value equal to 2^12, which is 4096.
However, this value exceeds the valid 12-bit range, as the maximum valid
phase value should be 4095.
2) Modified Condition (phase >= BIT(AD9832_PHASE_BITS)):
Ensures that the phase value is within the valid range, preventing
invalid datafrom being written.
Impact on Subsequent Logic: st->data = cpu_to_be16(addr | phase):
If the phase value is 2^12, i.e., 4096 (0001 0000 0000 0000), and addr
is AD9832_REG_PHASE0 (1100 0000 0000 0000), then addr | phase results in
1101 0000 0000 0000, occupying DB12. According to the section of WRITING
TO A PHASE REGISTER in the datasheet, the MSB 12 PHASE0 bits should be
DB11. The original condition leads to incorrect DB12 usage, which
contradicts the datasheet and could pose potential issues for future
updates if DB12 is used in such related cases.

in one of the two 16 bit IIO channels always being zero (when both are

This is because int is 32 bits wide on most architectures and in the
case of a little-endian machine the two most significant bytes would
occupy the buffer for the second channel as 'val' is being passed as a
void pointer to 'iio_push_to_buffers()'.
Fix by defining 'val' as u16. Tested working on ARM64.

The reason is the mentioned commit changed tegra_vi_graph_find_entity() to
search for an entity in the done notifier list:
> @@ -1464,7 +1464,7 @@ tegra_vi_graph_find_entity(struct tegra_vi_channel *chan,
> struct tegra_vi_graph_entity *entity;
> struct v4l2_async_connection *asd;
>
> - list_for_each_entry(asd, &chan->notifier.asc_list, asc_entry) {

> if (entity->asd.match.fwnode == fwnode)
> return entity;
This is not always correct, being tegra_vi_graph_find_entity() called in
three locations, in this order:
1. tegra_vi_graph_parse_one() -- called while probing
2. tegra_vi_graph_notify_bound() -- the .bound notifier op
3. tegra_vi_graph_build() -- called in the .complete notifier op
Locations 1 and 2 are called before moving the entity from waiting_list to
done_list, thus they won't find what they are looking for in
done_list. Location 3 happens afterwards and thus it is not broken, however
it means tegra_vi_graph_find_entity() should not search in the same list
every time.
The error appears at step 1: tegra_vi_graph_parse_one() iterates
recursively until it finds the entity already notified, which now never
happens.
Fix by passing the specific notifier list pointer to
tegra_vi_graph_find_entity() instead of the channel, so each caller can
search in whatever list is correct.
Also improve the tegra_vi_graph_find_entity() comment.

The current Kconfig symbol dependencies allow having the following Kconfig
symbol values
CONFIG_IPU_BRIDGE=m
CONFIG_VIDEO_IPU3_CIO2=y
CONFIG_CIO2_BRIDGE=n
This does not work as the IPU bridge API is conditional to
IS_ENABLED(CONFIG_IPU_BRIDGE). Fix this by changing the dependencies so
that CONFIG_IPU_BRIDGE can be separately selected.
The CONFIG_CIO2_BRIDGE symbol becomes redundant as a result and is
removed.

In commit 9011e49d54 ("modules: only allow symbol_get of
EXPORT_SYMBOL_GPL modules") the use of symbol_get is properly restricted
to GPL-only marked symbols. This interacts oddly with the DVB logic
which only uses dvb_attach() to load the dvb driver which then uses
symbol_get().
Fix this up by properly marking all of the dvb_attach attach symbols as
EXPORT_SYMBOL_GPL().

Here is the big set of tty and serial driver changes for 6.6-rc1.
Lots of cleanups in here this cycle, and some driver updates. Short
summary is:
- Jiri's continued work to make the tty code and apis be a bit more
sane with regards to modern kernel coding style and types
- cpm_uart driver updates
- n_gsm updates and fixes
- meson driver updates
- sc16is7xx driver updates
- 8250 driver updates for different hardware types
- qcom-geni driver fixes
- tegra serial driver change
- stm32 driver updates
- synclink_gt driver cleanups
- tty structure size reduction
All of these have been in linux-next this week with no reported issues.
The last bit of cleanups from Jiri and the tty structure size reduction
came in last week, a bit late but as they were just style changes and
size reductions, I figured they should get into this merge cycle so that
others can work on top of them with no merge conflicts.

We've received a fairly wide range of changes at this time, including
for ALSA and ASoC core, but all of them are rather small changes.
Here are some highlights:
ALSA / ASoC Core:
- Fixes of inconsistent locking around control API helpers
- A few new control API functions and cleanups
- Workarounds for potential UAFs by delayed kobj releases
- Unified PCM copy ops with iov_iter
- Continued efforts for ASoC API cleanups
ASoC:
- An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
some IIO changes
- Create a library function for intlog10() and use it in the NAU8825
driver
- Convert drivers to use the more modern maple tree register cache
- Lots of work on the SOF framework, AMD and Intel drivers, including a
lot of cleanup and new device support
- Standardization of the presentation of jacks from drivers
- Provision of some generic sound card DT properties
- Support for AMD Van Gogh, AMD machines with MAX98388 and NAU8821,
AWInic AW88261, Cirrus Logic CS35L36 and CS42L43, various Intel
platforms including AVS machines with ES8336 and RT5663, Mediatek
MT7986, NXP i.MX93, RealTek RT1017 and StarFive JH7110
Others:
- New test coverage including ASoC and topology tests in KUnit;
this also involves enabling UML builds of ALSA since that's the
default KUnit test environment which pulls in the addition of some
stubs to the driver
- More enhancement of pcmtest driver
- A few fixes / enhancements of MIDI 2.0 UMP core
- Using PCI definitions in allover HD-audio code
- Support for Cirrus CS35L56 and TI TAS2781 HD-audio sub-codecs
- CS35L41 HD-audio sub-codec improvements

"The drm core grew a new generic gpu virtual address manager, and new
execution locking helpers. These are used by nouveau now to provide

the usual amount of stuff across the board.

A mouse that uses a USB connection is called a "USB mouse" device (or
"USB mouse" for short), not a "mouse USB" device. By analogy, a WiFi
adapter that connects to the host computer via USB is a "USB wireless"
device, not a "wireless USB" device. (The latter term more properly
refers to a defunct Wireless USB specification, which described a
technology for sending USB protocol messages over an ultra wideband
radio link.)
Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a
"PCIe wireless" device, not a "wireless PCIe" device.
Rephrase the text in the kernel source where the word ordering is
wrong.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct rtllib_txb.

Tasklet irq_rx_tasklet is scheduled when hw is receiving frames. Function
_rtl92e_irq_rx_tasklet() is then called which calls then
_rtl92e_rx_normal(). In _rtl92e_rx_normal() all frames are processed by
rtllib_rx(). When ieee->iw_mode is IW_MODE_MESH the function returns
0. The calling function then calls: dev_kfree_skb_any() which clears
the skb. So the driver clears all packets received in this mode. Remove
dead code in mode IW_MODE_MESH.
