Revert "HID: logitech-hidpp: Enable HID++ for all the Logitech Bluetooth devices"
This reverts commit
532223c8ac57605a10e46dc0ab23dcf01c9acb43.
As reported in [0], hid-logitech-hidpp now binds on all bluetooth mice,
but there are corner cases where hid-logitech-hidpp just gives up on
the mouse. This leads the end user with a dead mouse.
Given that we are at -rc8, we are definitively too late to find a proper
fix. We already identified 2 issues less than 24 hours after the bug
report. One in that ->match() was never designed to be used anywhere else
than in hid-generic, and the other that hid-logitech-hidpp has corner
cases where it gives up on devices it is not supposed to.
So we have no choice but postpone this patch to the next kernel release.

This reverts commit

We need to revert commit
532223c8ac57 ("HID: logitech-hidpp: Enable HID++
for all the Logitech Bluetooth devices") because that commit might make
hid-logitech-hidpp bind on mice that are not well enough supported by
hid-logitech-hidpp, and the end result is that the probe of those mice
is now returning -ENODEV, leaving the end user with a dead mouse.
Given that commit
8544c812e43a ("HID: logitech-hidpp: Remove special-casing
of Bluetooth devices") is a direct dependency of
532223c8ac57, revert it
too.
Note that this also adapt according to commit

the devices that were removed from that commit too.
I have locally an MX Master and I tested this device with that revert,
ensuring we still have high-res scrolling.

The patch fixes it by returning from the ft260_xfer_status()

appropriate.
It does not apply to the i2c combined transactions when after
the write IO, the controller keeps the bus busy until the read

HID: ft260: remove SMBus Quick command support
The i2cdetect uses the SMBus Quick command by default to scan devices
on the I2C bus. The FT260 implements an I2C bus controller. The SMBus
is derived from I2C, but there are several differences between the
specifications of the two buses in the areas of timing, protocols,
operation modes, and electrical characteristics.
One of the differences is that the I2C devices allow the slave not
to ACK its slave address, but SMBus requires it to always ACK it as
a mechanism to detect a detachable device’s presence on the bus.
Since FT260 is the I2C bus controller, it does not acknowledge the
SMBus Quick write command, which sends a single bit to the device at
the place of the RD/WR bit.
The ft260 driver attempted to mimic the SMBus Quick Write functionality
by writing a single byte as the SMBus Byte Write command does.
Usually, one byte in the SMBus Quick Write will be fine. However, it may
cause problems with devices with a control register at offset 0, like
i2c muxes, for example, when scanned with the i2cdetect utility.
The i2cdetect with the "-r" option uses the SMBus Read Byte command,
which is a reasonable workaround. To prevent the I2C bus from locking
at write-only devices (most notably clock chips at address 0x69), use
the "-r" option in conjunction with scanning range parameters.
This patch removes the SMBus Quick command support.

HID: ft260: skip unexpected HID input reports
The FT260 is not supposed to generate unexpected HID reports. However,
in theory, the unsolicited HID Input reports can be issued by a specially
crafted malicious USB device masquerading as FT260 when the attacker has
physical access to the USB port. In this case, the read_buf pointer points
to the final data portion of the previous I2C Read transfer, and the memcpy
invoked in the ft260_raw_event() will try copying the content of the
unexpected report into the wrong location.
This commit sets the Read buffer pointer to NULL on the I2C Read
transaction completion and checks it in the ft260_raw_event() to detect
and skip the unsolicited Input report.

HID: ft260: support i2c reads greater than HID report size
A random i2c read operation in EEPROM devices is implemented as a dummy
write operation, followed by a current address read operation. The dummy
write operation is used to load the target byte or word address (a.k.a
offset) into the offset counter, from which the subsequent read operation
then reads.
To support longer than one HID report size random read, the ft260 driver
issues multiple pairs of i2c write offset + read data transactions of HID
report size so that the EEPROM device sees many i2c random read requests
from different offsets.
Two issues with the current implementation:
- This approach suffers from extra overhead caused by writing offset
requests.
- Necessity to handle offset per HID report in big-endian representation
as EEPROM devices expect. The current implementation does not do it and
correctly handles the reads up to 60 bytes only.
This patch addresses both issues by implementing more efficient approach.
It issues a single i2c read request of up to the EEPROM page size and then
waits for the data to arrive in multiple HID reports. For example, to read
the 256 bytes from a 24LC512 chip, which has 128 bytes page size, the old
method performs six ft260_i2c_write_read transactions while the new - two
only.

HID: ft260: support i2c writes larger than HID report size
To support longer than one HID report size write, the driver splits a
single i2c message data payload into multiple i2c messages of HID report
size. However, it does not replicate the offset bytes within the EEPROM
chip in every consequent HID report because it is not and should not be
aware of the EEPROM type. It breaks the i2c write message integrity and
causes the EEPROM device not to acknowledge the second HID report keeping
the i2c bus busy until the ft260 controller reports failure.
This patch preserves the i2c write message integrity by manipulating the
i2c flag bits across multiple HID reports to be seen by the EEPROM device
as a single i2c write transfer.

Sending a large amount of data at a low I2C clock rate saturates the

HID: ft260: ft260_xfer_status routine cleanup
After clarifying with FTDI's support, it turned out that the error
condition (bit 1) in byte 1 of the i2c status HID report is a status
bit reflecting all error conditions. When bits 2, 3, or 4 are raised
to 1, bit 1 is set to 1 also. Since the ft260_xfer_status routine tests
the error condition bit and exits in the case of an error, the program
flow never reaches the conditional expressions for 2, 3, and 4 bits when
any of them indicates an error state. Though these expressions are never
evaluated to true, they are checked several times per IO, increasing the
ft260_xfer_status polling cycle duration.
The patch removes the conditional expressions for 2, 3, and 4 bits in
byte 1 of the i2c status HID report.

ALSA: memalloc: Don't fall back for SG-buffer with IOMMU
When the non-contiguous page allocation for SG buffer allocation
fails, the memalloc helper tries to fall back to the old page
allocation methods. This would, however, result in the bogus page
addresses when IOMMU is enabled. Usually in such a case, the fallback
allocation should fail as well, but occasionally it succeeds and
hitting a bad access.
The fallback was thought for non-IOMMU case, and as the error from
dma_alloc_noncontiguous() with IOMMU essentially implies a fatal
memory allocation error, we should return the error straightforwardly
without fallback. This avoids the corner case like the above.
The patch also renames the local variable "dma_ops" with snd_ prefix
for avoiding the name conflict.

[Why]
The link enablement sequence can end up resetting the encoder while
the PHY symclk isn't yet on.
This means that waiting for symclk on will timeout, along with the reset
bit never asserting high.
This causes unnecessary delay when enabling the link and produces a
warning affecting multiple IGT tests.
[How]
Don't wait for the symclk to be on here because firmware already does.
Don't wait for reset if we know the symclk isn't on.
Split the reset into a helper function that checks the bit and decides
whether or not a delay is sufficient.

net/mlx5: Bridge, verify LAG state when adding bond to bridge
Mlx5 LAG is initialized asynchronously on a workqueue which means that for
a brief moment after setting mlx5 UL representors as lower devices of a
bond netdevice the LAG itself is not fully initialized in the driver. When
adding such bond device to a bridge mlx5 bridge code will not consider it
as offload-capable, skip creating necessary bookkeeping and fail any
further bridge offload-related commands with it (setting VLANs, offloading
FDBs, etc.). In order to make the error explicit during bridge
initialization stage implement the code that detects such condition during
NETDEV_PRECHANGEUPPER event and returns an error.

drm: rcar-du: Fix Kconfig dependency between RCAR_DU and RCAR_MIPI_DSI
When the R-Car MIPI DSI driver was added, it was a standalone encoder
driver without any dependency to or from the R-Car DU driver. Commit
957fe62d7d15 ("drm: rcar-du: Fix DSI enable & disable sequence") then
added a direct call from the DU driver to the MIPI DSI driver, without
updating Kconfig to take the new dependency into account. Fix it the
same way that the LVDS encoder is handled.

net: wwan: iosm: fix invalid mux header type
Data stall seen during peak DL throughput test & packets are
dropped by mux layer due to invalid header type in datagram.
During initlization Mux aggregration protocol is set to default
UL/DL size and TD count of Mux lite protocol. This configuration
mismatch between device and driver is resulting in data stall/packet
drops.
Override the UL/DL size and TD count for Mux aggregation protocol.
