The iio_dmaengine_buffer_setup_ext() function is public and should be

speaking, it can be any device that is a valid DMA channel consumer.

Simplify the code by using devm_regulator_get_enable_read_voltage().
There is a small change in behavior. Before, all errors from
devm_regulator_get_optional() were ignored and assumed to mean that
the external reference supply was absent. Now, only -ENODEV is checked
and other errors will cause a failure to probe. So now, this will
catch errors, like using the wrong data type for the devicetree
property.

The continual trickle of small conversion patches is grating on me, and
is really not helping. Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:
/*
* .remove_new() is a relic from a prototype conversion of .remove().
* New drivers are supposed to implement .remove(). Once all drivers are
* converted to not use .remove_new any more, it will be dropped.
*/
This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.
I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.
Then I just removed the old (sic) .remove_new member function, and this
is the end result. No more unnecessary conversion noise.

core: add of based component probing
Some devices are designed and manufactured with some components having
multiple drop-in replacement options. These components are often
connected to the mainboard via ribbon cables, having the same signals
and pin assignments across all options. These may include the display
panel and touchscreen on laptops and tablets, and the trackpad on
laptops. Sometimes which component option is used in a particular device
can be detected by some firmware provided identifier, other times that
information is not available, and the kernel has to try to probe each
device.
Instead of a delicate dance between drivers and device tree quirks, this
change introduces a simple I2C component probe function. For a given
class of devices on the same I2C bus, it will go through all of them,
doing a simple I2C read transfer and see which one of them responds. It
will then enable the device that responds.

processing occurs then. The bprintf() was added for consistency but

Pull x86 fixes from Borislav Petkov:
- Add a terminating zero end-element to the array describing AMD CPUs
affected by erratum 1386 so that the matching loop actually
terminates instead of going off into the weeds
- Update the boot protocol documentation to mention the fact that the
preferred address to load the kernel to is considered in the
relocatable kernel case too
- Flush the memory buffer containing the microcode patch after applying
microcode on AMD Zen1 and Zen2, to avoid unnecessary slowdowns
- Make sure the PPIN CPU feature flag is cleared on all CPUs if PPIN
has been disabled

x86/cpu: Fix PPIN initialization
The point behind strscpy() was to once and for all avoid all the
problems with 'strncpy()' and later broken "fixed" versions like
strlcpy() that just made things worse.
So strscpy not only guarantees NUL-termination (unlike strncpy), it also
doesn't do unnecessary padding at the destination. But at the same time
also avoids byte-at-a-time reads and writes by _allowing_ some extra NUL
writes - within the size, of course - so that the whole copy can be done
with word operations.
It is also stable in the face of a mutable source string: it explicitly
does not read the source buffer multiple times (so an implementation
using "strnlen()+memcpy()" would be wrong), and does not read the source
buffer past the size (like the mis-design that is strlcpy does).
Finally, the return value is designed to be simple and unambiguous: if
the string cannot be copied fully, it returns an actual negative error,
making error handling clearer and simpler (and the caller already knows
the size of the buffer). Otherwise it returns the string length of the
result.
However, there was one final stability issue that can be important to
callers: the stability of the destination buffer.
In particular, the same way we shouldn't read the source buffer more
than once, we should avoid doing multiple writes to the destination
buffer: first writing a potentially non-terminated string, and then
terminating it with NUL at the end does not result in a stable result
buffer.
Yes, it gives the right result in the end, but if the rule for the
destination buffer was that it is _always_ NUL-terminated even when
accessed concurrently with updates, the final byte of the buffer needs
to always _stay_ as a NUL byte.
[ Note that "final byte is NUL" here is literally about the final byte
in the destination array, not the terminating NUL at the end of the
string itself. There is no attempt to try to make concurrent reads and
writes give any kind of consistent string length or contents, but we
do want to guarantee that there is always at least that final
terminating NUL character at the end of the destination array if it
existed before ]
This is relevant in the kernel for the tsk->comm[] array, for example.
Even without locking (for either readers or writers), we want to know
that while the buffer contents may be garbled, it is always a valid C
string and always has a NUL character at 'comm[TASK_COMM_LEN-1]' (and
never has any "out of thin air" data).
So avoid any "copy possibly non-terminated string, and terminate later"
behavior, and write the destination buffer only once.

bprintf() is unused. Remove it. It was added in the commit 4370aa4aa7
("vsprintf: add binary printf") but as far as I can see was never used,
unlike the other two functions in that patch.

- Remove a leftover struct from when the cqwait registered waiting was

- Fix for an issue introduced in this merge window, where nop->fd might
be used uninitialized. Ensure it's always set.
- Add capping of the task_work run in local task_work mode, to prevent
bursty and long chains from adding too much latency.
- Work around xa_store() leaving ->head non-NULL if it encounters an
allocation error during storing. Just a debug trigger, and can go
away once xa_store() behaves in a more expected way for this
condition. Not a major thing as it basically requires fault injection
to trigger it.
- Fix a few mapping corner cases
- Fix KCSAN complaint on reading the table size post unlock. Again not
a "real" issue, but it's easy to silence by just keeping the reading
inside the lock that protects it.
