Linus Torvalds 443d11297b Driver core fixes for 5.11-rc5
Here are some small driver core fixes for 5.11-rc5 that resolve some
 reported problems:
 	- revert of a -rc1 patch that was causing problems with some
 	  machines
 	- device link device name collision problem fix (busses only
 	  have to name devices unique to their bus, not unique to all
 	  busses)
 	- kernfs splice bugfixes to resolve firmware loading problems
 	  for Qualcomm systems.
 	- other tiny driver core fixes for minor issues reported.
 
 All of these have been in linux-next with no reported problems.

Andrey Konovalov 76bc99e81a kasan: fix HW_TAGS boot parameters
The initially proposed KASAN command line parameters are redundant.

This change drops the complex "kasan.mode=off/prod/full" parameter and
adds a simpler kill switch "kasan=off/on" instead.  The new parameter
together with the already existing ones provides a cleaner way to
express the same set of features.

The full set of parameters with this change:

  kasan=off/on             - whether KASAN is enabled
  kasan.fault=report/panic - whether to only print a report or also panic
  kasan.stacktrace=off/on  - whether to collect alloc/free stack traces

Default values:

  kasan=on
  kasan.fault=report
  kasan.stacktrace=on  (if CONFIG_DEBUG_KERNEL=y)
  kasan.stacktrace=off (otherwise)

and has the 128bit PROM layout.

Mikulas Patocka 5c02406428 dm integrity: conditionally disable "recalculate" feature
Otherwise a malicious user could (ab)use the "recalculate" feature
that makes dm-integrity calculate the checksums in the background
while the device is already usable. When the system restarts before all
checksums have been calculated, the calculation continues where it was
interrupted even if the recalculate feature is not requested the next
time the dm device is set up.

Disable recalculating if we use internal_hash or journal_hash with a
key (e.g. HMAC) and we don't have the "legacy_recalculate" flag.

This may break activation of a volume, created by an older kernel,
that is not yet fully recalculated -- if this happens, the user should
add the "legacy_recalculate" flag to constructor parameters.

Saravana Kannan e020ff611b driver core: Fix device link device name collision
The device link device's name was of the form:
<supplier-dev-name>--<consumer-dev-name>

This can cause name collision as reported here [1] as device names are
not globally unique. Since device names have to be unique within the
bus/class, add the bus/class name as a prefix to the device names used to
construct the device link device name.

So the devuce link device's name will be of the form:
<supplier-bus-name>:<supplier-dev-name>--<consumer-bus-name>:<consumer-dev-name>

Stephan Gerhold b6bc1b4ffa dt-bindings: iio: accel: bma255: Fix bmc150/bmi055 compatible
The bmc150-accel-i2c.c driver has an "_accel" suffix for the
compatibles of BMC150 and BMI055. This is necessary because BMC150
contains both accelerometer (bosch,bmc150_accel) and magnetometer
(bosch,bmc150_magn) and therefore "bosch,bmc150" would be ambiguous.

However, the binding documentation suggests using "bosch,bmc150".
Add the "_accel" suffix for BMC150 and BMI055 so the binding docs
match what is expected by the driver.

Tariq Toukan 25537d71e2 net: Allow NETIF_F_HW_TLS_TX if IP_CSUM && IPV6_CSUM
Cited patch below blocked the TLS TX device offload unless HW_CSUM
is set. This broke devices that use IP_CSUM && IP6_CSUM.
Here we fix it.

Note that the single HW_TLS_TX feature flag indicates support for
both IPv4/6, hence it should still be disabled in case only one of
(IP_CSUM | IPV6_CSUM) is set.

 All changes are device-specific small fixes, and majority of
 commits are for ASoC while USB-audio got a bit large changes for
 addressing the regression for devices with quirks.

David Woodhouse b36b0fe96a x86/xen: Add xen_no_vector_callback option to test PCI INTX delivery
It's useful to be able to test non-vector event channel delivery, to make
sure Linux will work properly on older Xen which doesn't have it.

It's also useful for those working on Xen and Xen-compatible hypervisors,
because there are guest kernels still in active use which use PCI INTX
even when vector delivery is available.

MPU-6880 seems to be very similar to MPU-6500 / MPU-6050 and it works
fine with some minor additions for the mpu6050 driver.
Add a compatible for it to the binding documentation.

Jonathan Cameron 749787477a dt-bindings:iio:gyro:invensense,mpu3050: txt to yaml format conversion.
Very similar to the mpu6050 binding.
Only unusual element is the i2c-gate section.
Example tweaked a little to include a real device behind the gate.

As Rob Herring suggested, dropped use of explicit i2c-gate yaml
binding in favour of just using the i2c-controller.yaml binding
directly.

Jonathan Cameron 44fd881338 dt-bindings:iio:imu:invensense,mpu6050: txt to yaml conversion
As Rob Herring suggested, this no long requires the explicit
i2c-gate binding, but instead just used i2c-controller.yaml
directly.

2 prior examples combinded into one as a single example can show
all of the binding elements as long as the right part is selected.

Lars-Peter Clausen d0dc4c80b9 dt-bindings:iio:xilinx-xadc: Add Xilinx System Management Wizard binding docs
Add binding documentation for the Xilinx System Management Wizard. The
Xilinx System Management Wizard is a AXI frontend for the Xilinx System
Monitor found in the UltraScale and UltraScale+ FPGAs.

The System Monitor is the equivalent to the Xilinx XADC found in their
previous generation of FPGAs and their external and internal interfaces are
very similar. For this reason the share the same binding documentation. But
since they are not 100% compatible and software will have to know about the
differences they use a different compatible string.
