Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.4-rc1.
Once again, a busy development cycle, with lots of changes happening
in the driver core in the quest to be able to move "struct bus" and
"struct class" into read-only memory, a task now complete with these
changes.
This will make the future rust interactions with the driver core more
"provably correct" as well as providing more obvious lifetime rules
for all busses and classes in the kernel.
The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most
of them actually did so.
Other than those changes, included in here are a small set of other
things:
- kobject logging improvements
- cacheinfo improvements and updates
- obligatory fw_devlink updates and fixes
- documentation updates
- device property cleanups and const * changes
- firwmare loader dependency fixes.
All of these have been in linux-next for a while with no reported
problems"

Since commit 8b41fc4454e ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.
So remove it in the files in this commit, none of which can be built as
modules.

When the SOC approaches zero, an integer overflows in the columb
counter causing the driver to react poorly. This makes the driver
think it's at (above) the fully charged capacity when in fact it's
zero. It would then write this full capacity to NVRAM which would be
used on boot if the device remained off for less than 5 hours and
not plugged in.
This can be fixed and guarded against by doing the following:
- Changing the type of tmp in rk817_read_or_set_full_charge_on_boot()
to be an int instead of a u32. That way we can account for negative
numbers.
- Guard against negative values for the full charge on boot by setting
the charge to 0 if the system charge reports less than 0.
- Catch scenarios where the battery voltage is below the design
minimum voltage and set the system SOC to 0 at that time and update
the columb counter with a charge level of 0.
- Change the off time value from 5 hours to 30 minutes before we
recalculate the current capacity based on the OCV tables.
These changes allow the driver to operate better at low voltage/low
capacity conditions.

x86 ACPI boards which ship with only Android as their factory image may
have pretty broken ACPI tables. This includes broken _AEI ACPI GPIO event
handlers, which are normally used to listen to the micro-USB ID pin and:
1. Switch the USB-mux to the host / device USB controllers
2. Disable Vbus path before enabling the 5V boost (AXP reg 0x30 bit 7)
3. Turn 5V Vboost on / off
On non broken systems where this is not done through an ACPI GPIO event
handler, there is an ACPI INT3496 device describing the involved GPIOs
which are handled by the extcon-intel-int3496 driver; and axp288-charger.ko
listens to this extcon-device and disables the Vbus path when necessary.
On x86 Android boards, with broken ACPI GPIO event handlers, these are
disabled by acpi_quirk_skip_gpio_event_handlers() and an intel-int3496
extcon device is manually instantiated by x86-android-tablets.ko .
Add support to the axp288-charger code for this setup, so that it
properly disables the Vbus path when necessary. Note this uses
acpi_quirk_skip_gpio_event_handlers() to identify these systems,
to avoid the need to add a separate DMI match table for this.

Constant battery data is available through power-supply's simple-battery
API. This works automatically, so the manual handling can be removed
without loosing any feature :)
Note, that the POWER_SUPPLY_STATUS_FULL check for the level variable can
be dropped, since the variable is never written. It can be re-introduced
properly once the driver gets functionality to calculate the current
charge level. Apart from that the check must be done fuzzy anyways,
since charge estimation usually is not precise enough to always return
exactly the full charge capacity for a full battery.

The thermal zone device structure is exposed to the different drivers
and obviously they access the internals while that should be
restricted to the core thermal code.
In order to self-encapsulate the thermal core code, we need to prevent
the drivers accessing directly the thermal zone structure and provide
accessor functions to deal with.
Use the devdata accessor introduced in the previous patch.

There is an null pointer check order issue here: if we have to
check !desc and !desc->name anyway, check it before dereferencing it in
pr_warn().

Since this driver can only be built-in, it fails to link when
the I2C layer is in a loadable module:
x86_64-linux-ld: drivers/power/reset/odroid-go-ultra-poweroff.o: in function `odroid_go_ultra_poweroff_get_pmic_device':
odroid-go-ultra-poweroff.c:(.text+0x30): undefined reference to `i2c_find_device_by_fwnode'
Tighten the dependency to only allow enabling
POWER_RESET_ODROID_GO_ULTRA_POWEROFF is I2C is built-in as well.

The Hardkernel Odroid Go Ultra poweroff scheme requires requesting a poweroff
to its two PMICs in order, this represents the poweroff scheme needed to complete
a clean poweroff of the system.
This implement this scheme by implementing a self registering driver to permit
using probe defer until both pmics are finally probed.
