c84aaa4da1 ABI: sysfs-class-gnss: use wildcards on What definitions
An "N" upper letter is not a wildcard, nor can easily be identified
by script, specially since the USB sysfs define things like.
bNumInterfaces. Use, instead, <N>, in order to let script/get_abi.pl

08981d29c3 ABI: sysfs-bus-rapidio: use wildcards on What definitions
While humans may be able to understand that something like:

	/sys/bus/rapidio/devices/nn:d:iiii

could actually mean:

	/sys/bus/rapidio/devices/00:e:0000

This is something that computers can't easily identify. As
get_abi.pl needs to convert it into a regex, change What: lines
to:

	/sys/bus/rapidio/devices/<nn>:<d>:<iiii>

Which is the commonly-used pattern on ABI files for wildcards.

7065f92255 driver core: Clarify that dev_err_probe() is OK even w/out -EPROBE_DEFER
There is some debate about whether it's deemed acceptable to call
dev_err_probe() if you know that the error code can never be
-EPROBE_DEFER. Clarify in the function comments that this is
OK. Specifically this makes us able to transform code like this:

  ret = do_something_that_cant_defer();
  if (ret < 0) {
    dev_err(dev, "The foo failed to bar (%pe)\n", ERR_PTR(ret));
    return ret;
  }

to code like this:
  ret = do_something_that_cant_defer();
  if (ret < 0)
    return dev_err_probe(dev, ret, "The foo failed to bar\n");

It is also possible that in the future folks might want a CONFIG
option to strip out all probe error strings to save space (keeping
non-probe errors) with the argument that probe errors rarely happen
after bringup. Having probe errors reported with a consistent function
would allow that.

8988bacd60 kobject: unexport kobject_create() in kobject.h
The function kobject_create() is only used by one caller,
kobject_create_and_add(), no other driver uses it, nor is exported to
other modules.

However it's still exported in kobject.h, and can sometimes confuse
users of kobject.h.

Since all users should call kobject_create_and_add(), or if extra
attributes are needed, should alloc the memory manually then call
kobject_init_and_add().

d8e988b62f Misc driver fix for 5.15-rc1
Here is a single patch for 5.15-rc1, for the lkdtm misc driver.
 
 It resolves a build issue that many people were hitting with your
 current tree, and Kees and others felt would be good to get merged
 before -rc1 comes out, to prevent them from having to constantly hit it
 as many development trees restart on -rc1, not older -rc releases.
 
 It has NOT been in linux-next, but has passed 0-day testing and looks
 "obviously correct" when reviewing it locally :)

4a86d41404 perf tools: Allow build-id with trailing zeros
Currently perf saves a build-id with size but old versions assumes the
size of 20.  In case the build-id is less than 20 (like for MD5), it'd
fill the rest with 0s.

I saw a problem when old version of perf record saved a binary in the
build-id cache and new version of perf reads the data.  The symbols
should be read from the build-id cache (as the path no longer has the
same binary) but it failed due to mismatch in the build-id.

  symsrc__init: build id mismatch for /home/namhyung/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf.

The build-id event in the data has 20 byte build-ids, but it saw a
different size (16) when it reads the build-id of the elf file in the
build-id cache.

  $ readelf -n ~/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf

      Build ID: 53e4c2f42a4c61a2d632d92a72afa08f

Let's fix this by allowing trailing zeros if the size is different.

99fc5941b8 perf tools: Fix hybrid config terms list corruption
A config terms list was spliced twice, resulting in a never-ending loop
when the list was traversed. Fix by using list_splice_init() and copying
and freeing the lists as necessary.

This patch also depends on patch "perf tools: Factor out
copy_config_terms() and free_config_terms()"

Example on ADL:
