Hi Linus,

Please pull from the tag

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
acpi-6.15-rc1

with top-most commit 8b30d2a3962ae07e67aee90d6698a6a68e771c6c

Merge branches 'acpi-x86', 'acpi-platform-profile', 'acpi-apei' and 'acpi-misc'

on top of commit 80e54e84911a923c40d7bee33a34c1b4be148d7a

Linux 6.14-rc6

to receive ACPI updates for 6.15-rc1.

>From the functional perspective, the most significant changes here are
the ACPI fan driver update allowing it to handle fans with fine-grained
state checking supported, but without fine-grained control, and the
ACPI button driver update making it subscribe to system event
notifications (in addition to device notifications) which on some
systems is requisite for waking up the system from sleep.

The rest is fixes and cleanups including removal of some dead code.

Specifics:

- Use the str_on_off() helper function instead of hard-coded strings in
the ACPI power resources handling code (Thorsten Blum).

- Add fan speed reporting for ACPI fans that have _FST, but otherwise
do not support the entire ACPI 4 fan interface (Joshua Grisham).

- Fix a stale comment regarding trip points in acpi_thermal_add() that
diverged from the commented code after removing _CRT evaluation from
acpi_thermal_get_trip_points() (xueqin Luo).

- Make ACPI button driver also subscribe to system events (Mario
Limonciello).

- Use the str_yes_no() helper function instead of hard-coded strings in
the ACPI backlight (video) driver (Thorsten Blum).

- Add a missing header file include to the x86 arch CPPC code (Mario
Limonciello).

- Rework the sysfs attributes implementation in the ACPI platform-profile
driver and improve the unregistration code in it (Nathan Chancellor,
Kurt Borja).

- Prevent the ACPI HED driver from being built as a module and change
its initcall level to subsys_initcall to avoid initialization ordering
issues related to it (Xiaofei Tan).

- Update a maintainer email address in the ACPI PMIC entry in
MAINTAINERS (Mika Westerberg).

- Address a GCC 15's -Wunterminated-string-initialization warning in
the core PNP subsystem code and remove some dead code from it (Kees
Cook, David Alan Gilbert).

Thanks!
