7169a78e39 iio: adc: max11100: Use devm_ functions for rest of probe()
By using devm_add_action_or_reset() to manage the regulator disable,
it becomes simple to use managed functions for all of remove.
This simplifies error handling and allows us to drop the remove()
function entirely.

38e9d5caee iio: chemical: sgp30: Drop use of %hx in format string.
Since:
commit cbacb5ab0a ("docs: printk-formats: Stop encouraging use of
unnecessary %h[xudi] and %hh[xudi]")
use of these format strings has been discouraged.

As there are only a few such uses in IIO, lets clear them all out and
avoid chance of them getting copied into new drivers.

3d8ad94bb1 iio: accel: st_sensors: Support generic mounting matrix
The ST accelerators support a special type of quirky mounting matrix found
in ACPI systems, but not a generic mounting matrix such as from the device
tree.

Augment the ACPI hack to be a bit more generic and accept a mounting
matrix from device properties.

This makes it possible to fix orientation on the Ux500 HREF device.

53ebee9499 iio: afe: iio-rescale: Support processed channels
It happens that an ADC will only provide raw or processed
voltage conversion channels. (adc/ab8500-gpadc.c).
On the Samsung GT-I9070 this is used for a light sensor
and current sense amplifier so we need to think of something.

The idea is to allow processed channels and scale them
with 1/1 and then the rescaler can modify the result
on top.

for reading a batch of data (status, temperature, gyroscopes,
accelerometers, time stamp/data counter, and CRC code), which does not
require a stall time between each 16-bit segment and only requires one
command on the DIN line to initiate. Devices supporting this mode
are:

 * adis16495-1
 * adis16495-2
 * adis16495-3
 * adis16497-1

I have a handful of RISC-V related fixes:
 
 * A fix to avoid errors when the stack tracing code is tracing itself.
 * A fix to resurrect the memtest= kernel command line argument on
   RISC-V, which was briefly enabled during the merge window before a
   refactoring disabled it.
 * A build fix and some warning cleanups.

 "This week's pile mitigates some decades-old problems in how extent

  The most user-notable change here is to point users at our (new) IRC

  and if you don't kowtow, they'll expel everyone and take over your

ddc4739169 seccomp: Refactor notification handler to prepare for new semantics
This refactors the user notification code to have a do / while loop around
the completion condition. This has a small change in semantic, in that
previously we ignored addfd calls upon wakeup if the notification had been
responded to, but instead with the new change we check for an outstanding
addfd calls prior to returning to userspace.

Rodrigo Campos also identified a bug that can result in addfd causing
an early return, when the supervisor didn't actually handle the
syscall [1].

000ac42953 selftests: kvm: fix overlapping addresses in memslot_perf_test
vm_create allocates memory and maps it close to GPA.  This memory
is separate from what is allocated in subsequent calls to
vm_userspace_mem_region_add, so it is incorrect to pass the
test memory size to vm_create_default.  Just pass a small
fixed amount of memory which can be used later for page table,
otherwise GPAs are already allocated at MEM_GPA and the
test aborts.
