Couple of fixes for HID-core:
- use of kvzalloc in case memory gets too fragmented (Hailong Liu)
- retrieve the device firmware node in the child HID device (Danny
Kaehn)
In kbd_rgb_mode_store the dev_get_drvdata() call was assuming the device
data was asus_wmi when it was actually led_classdev.
This patch corrects this by making the correct chain of calls to get the
asus_wmi driver data.

Smatch complains that 'str' can be used without being initialized:
drivers/platform/x86/intel/intel_plr_tpmi.c:178 plr_print_bits()
error: uninitialized symbol 'str'.
In this loop, we iterate over all the set bits and print the name of the
bit. The intention is that if there is a bit which is between 0-31 we
look for the name in the first array plr_coarse_reasons[] which has 10
elements. If the bit is in the 32-63 range we look for it in the
plr_fine_reasons[] array which has 30 elements. If the bit is in the
invalid ranges, 10-31 or 62-63, then we should print "UNKNOWN(%d)".
The problem is that 'str' needs to be initialized at the start of each
iteration, otherwise if we can't find the string then instead of printing
"UNKNOWN(%d)", we will re-print whatever the previous bit was.

Switching to transparent mode leads to a loss of link synchronization,
so prevent doing this on an active link. This happened at least on an
Intel N100 system / DELL UD22 dock, the LTTPR residing either on the
host or the dock. To fix the issue, keep the current mode on an active
link, adjusting the LTTPR count accordingly (resetting it to 0 in
transparent mode).
v2: Adjust code comment during link training about reiniting the LTTPRs.

Regularly retraining a link during an atomic commit happens with the
given pipe/link already disabled and hence intel_dp->link_trained being
false. Ensure this also for retraining a DP SST link via direct calls to
the link training functions (vs. an actual commit as for DP MST). So far
nothing depended on this, however the next patch will depend on
link_trained==false for changing the LTTPR mode to non-transparent.

Kconfig simplifies expressions, but redundant '&&' and '||' operators
involving constant symbols 'y' and 'n' are sometimes trimmed and
sometimes not.
[Test Code]
config DEP
def_bool y
config A
bool "A"
depends on DEP && y
config B
bool "B"
depends on DEP && y && y
[Result]
$ make helpnewconfig
[ snip ]
-----
There is no help available for this option.
Symbol: A [=n]
Type : bool
Defined at Kconfig:4
Prompt: A
Depends on: DEP [=y] && y [=y]

-----
There is no help available for this option.
Symbol: B [=n]
Type : bool
Defined at Kconfig:8
Prompt: B
Depends on: DEP [=y]
Location:
-> B (B [=n])
-----
The dependency for A, 'DEP && y', remains as-is, while that for B,
'DEP && y && y', has been reduced to 'DEP'.
Currently, expr_eliminate_dups() calls expr_eliminate_yn() only when
trans_count != 0, in other words, only when expr_eliminate_dups1() has
trimmed at least one leaf. It fails to trim a single '&& y', etc.
To fix this inconsistent behavior, expr_eliminate_yn() should be called
at least once even if no leaf has been trimmed.

${DEBFULLNAME-${user}} falls back to ${user} when DEBFULLNAME is unset.
It is more reasonable to do so when DEBFULLNAME is unset or null.
Otherwise, the command:
$ DEBFULLNAME= make deb-pkg
will leave the name field blank.
The same applies to KBUILD_BUILD_USER and KBUILD_BUILD_HOST.

As commit afa974b771 ("kbuild: add real-prereqs shorthand for
$(filter-out FORCE,$^)") explained, $(real-prereqs) is not just a list
of objects when linking a multi-object module. If a single-object module
is turned into a multi-object module, $^ (and therefore $(real-prereqs)
as well) contains header files recorded in the *.cmd file. Such headers
must be filtered out.
Now that a DTB can be built either from a single source or multiple
source files, the same issue can occur.
Consider the following scenario:
First, foo.dtb is implemented as a single-blob device tree.
The code looks something like this:
[Sample Code 1]
Makefile:
dtb-y += foo.dtb
foo.dts:
#include <dt-bindings/gpio/gpio.h>
/dts-v1/;
/ { };
When it is compiled, .foo.dtb.cmd records that foo.dtb depends on
scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h.
Later, foo.dtb is split into a base and an overlay. The code looks
something like this:
[Sample Code 2]
Makefile:
dtb-y += foo.dtb
foo-dtbs := foo-base.dtb foo-addon.dtbo
foo-base.dts:
#include <dt-bindings/gpio/gpio.h>
/dts-v1/;
/ { };
foo-addon.dtso:
/dts-v1/;
/plugin/;
/ { };
If you rebuild foo.dtb without 'make clean', you will get this error:
Overlay 'scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h' is incomplete
$(real-prereqs) contains not only foo-base.dtb and foo-addon.dtbo but
also scripts/dtc/include-prefixes/dt-bindings/gpio/gpio.h, which is
passed to scripts/dtc/fdtoverlay.

Instead of using a single table containing information about various
touchscreens and enums to match the driver ID table data with chip
information define individual per-protocol instances of
usbtouch_device_info structure and reference them directly from
the usbtouch_devices ID table. This is simpler, safer, and uses less
memory in case some protocols are disabled.

There's some quite exciting core work in this release, we've got the
beginnings of support for hardware initiated transfers which is itself
independently useful for optimising fast paths in existing drivers.
We also have a rework of the DMA mapping which allows finer grained
decisions about DMA mapping messages and also helps remove some bodges
that we'd had.
Otherwise it's a fairly quiet release, a few new drivers and features
for existing drivers, together with various cleanups and DT binding
conversions.
One regmap SPI fix made it's way in here too which I should probably
have sent as a regmap fix instead.
- Support for pre-optimising messages, reducing the overhead for
messages that are repeatedly used (eg, reading the interrupt status
from a device). This will also be used for hardware initiated
transfers in future.
- A reworking of how DMA mapping is done, introducing a new helper and
allowing the DMA mapping decision to be done per transfer instead of
per message.
- Support for Atmel SAMA7D64, Freescale LX2160A DSPI and WCH CH341A.

Pull spi updates from Mark Brown:
"There's some quite exciting core work in this release, we've got the
beginnings of support for hardware initiated transfers which is itself
independently useful for optimising fast paths in existing drivers.
We also have a rework of the DMA mapping which allows finer grained
decisions about DMA mapping messages and also helps remove some bodges
that we'd had.
Otherwise it's a fairly quiet release, a few new drivers and features
for existing drivers, together with various cleanups and DT binding
conversions.
One regmap SPI fix made it's way in here too which I should probably
have sent as a regmap fix instead.
Summary:
- Support for pre-optimising messages, reducing the overhead for
messages that are repeatedly used (eg, reading the interrupt status
from a device). This will also be used for hardware initiated
transfers in future.
- A reworking of how DMA mapping is done, introducing a new helper
and allowing the DMA mapping decision to be done per transfer
instead of per message.
- Support for Atmel SAMA7D64, Freescale LX2160A DSPI and WCH CH341A"

This s a very quiet release for the regulator API, we have a few new
devices (most of which are just ID updates) and one new fairly
specialist core feature for use in interrupt context.
- An API allowing lockless enable/disable for regulators acquired in
exclusive mode, for use in interrupt contexts.
- A rewrite of the MedaTek DVFSRC regulator driver which apparently
never worked.
- Support for Mediaktek MT6312, Qualcomm QCA6390 and WCN7850, Renesas
RZ/G2L USB VBUS regulator and ST Microelectronics STM32MP13.

There's one new feature here, a regmap_multi_reg_read() matching the
existing write function which has some IIO users coming. This allows
atomic reads from multiple registers without the need to wrap a higher
level lock in the client driver just for regmap (which already has locks
anyway). We also have one fix for the KUnit tests, and a bunch of
cleanups.
