The upcoming mt7988 has different temperature coefficients so we
cannot use constants in the functions lvts_golden_temp_init,
lvts_golden_temp_init and lvts_raw_to_temp anymore.
Add a field in the lvts_ctrl pointing to the lvts_data which now
contains the soc-specific temperature coefficents.
To make the code better readable, rename static int coeff_b to
golden_temp_offset, COEFF_A to temp_factor and COEFF_B to temp_offset.

The dev->id value comes from ida_alloc() so it's a number between zero
and INT_MAX. If it's too high then these sprintf()s will overflow.

Amit Kucheria has not been participating in kernel development in any
way or form for quite some time, so it is not useful to list him as a
designated reviewer for the thermal subsystem or as the thermal zone DT
binding maintainer.
Remove him from the THERMAL entry in MAINTAINERS and list Daniel Lezcano
as the new thermal zone DT binding maintainer.

Add a wrapper around for_each_thermal_trip(), called
thermal_zone_for_each_trip(), that will invoke the former under the
thermal zone lock and pass its return value to the caller.
Two drivers will be modified subsequently to use this new function.
No functional impact.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
amlogic_thermal_disable() always returned zero. Change it to return no
value and then trivially convert the driver to .remove_new() and fix a
whitespace inconsitency en passant.

from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Add new helper functions, thermal_bind_cdev_to_trip() and
thermal_unbind_cdev_from_trip(), to allow a trip pointer to be used for
binding a cooling device to a trip point and unbinding it, respectively,
and redefine the existing helpers, thermal_zone_bind_cooling_device()
and thermal_zone_unbind_cooling_device(), as wrappers around the new
ones, respectively.
No intentional functional impact.

Replace the integer trip number stored in struct thermal_instance with
a pointer to the relevant trip and adjust the code using the structure
in question accordingly.
The main reason for making this change is to allow the trip point to
cooling device binding code more straightforward, as illustrated by
subsequent modifications of the ACPI thermal driver, but it also helps
to clarify the overall design and allows the governor code overhead to
be reduced (through subsequent modifications).
The only case in which it adds complexity is trip_point_show() that
needs to walk the trips[] table to find the index of the given trip
point, but this is not a critical path and the interface that
trip_point_show() belongs to is problematic anyway (for instance, it
doesn't cover the case when the same cooling devices is associated
with multiple trip points).
This is a preliminary change and the affected code will be refined by
a series of subsequent modifications of thermal governors, the core and
the ACPI thermal driver.
The general functionality is not expected to be affected by this change.

It is invalid to call for_each_thermal_trip() on an unregistered thermal
zone anyway, and as per thermal_zone_device_register_with_trips(), the
trips[] table must be present if num_trips is greater than zero for the
given thermal zone.
Hence, the trips check in for_each_thermal_trip() is redundant and so it
can be dropped.

After recent changes, thermal_zone_get_trip() cannot fail, as invoked
from thermal_zone_device_register_with_trips(), so the only role of
the trips_disabled bitmask is struct thermal_zone_device is to make
handle_thermal_trip() skip trip points whose temperature was initially
zero. However, since the unit of temperature in the thermal core is
millicelsius, zero may very well be a valid temperature value at least
in some usage scenarios and the trip temperature may as well change
later. Thus there is no reason to permanently disable trip points
with initial temperature equal to zero.
Accordingly, drop the trips_disabled bitmask along with the code
related to it.

Pull tracing fixes from Steven Rostedt:
- Fix the "bytes" output of the per_cpu stat file
The tracefs/per_cpu/cpu*/stats "bytes" was giving bogus values as the
accounting was not accurate. It is suppose to show how many used
bytes are still in the ring buffer, but even when the ring buffer was
empty it would still show there were bytes used.
- Fix a bug in eventfs where reading a dynamic event directory (open)
and then creating a dynamic event that goes into that diretory screws
up the accounting.
On close, the newly created event dentry will get a "dput" without
ever having a "dget" done for it. The fix is to allocate an array on
dir open to save what dentries were actually "dget" on, and what ones
to "dput" on close.

Pull cxl fixes from Dan Williams:
"A collection of regression fixes, bug fixes, and some small cleanups
to the Compute Express Link code.
The regressions arrived in the v6.5 dev cycle and missed the v6.6
merge window due to my personal absences this cycle. The most
important fixes are for scenarios where the CXL subsystem fails to
parse valid region configurations established by platform firmware.
This is important because agreement between OS and BIOS on the CXL
configuration is fundamental to implementing "OS native" error
handling, i.e. address translation and component failure
identification.
Other important fixes are a driver load error when the BIOS lets the
Linux PCI core handle AER events, but not CXL memory errors.
The other fixex might have end user impact, but for now are only known
to trigger in our test/emulation environment.
Summary:
- Fix multiple scenarios where platform firmware defined regions fail
to be assembled by the CXL core.
- Fix a spurious driver-load failure on platforms that enable OS
native AER, but not OS native CXL error handling.
- Fix a regression detecting "poison" commands when "security"
commands are also defined.
- Fix a cxl_test regression with the move to centralize CXL port
register enumeration in the CXL core.
- Miscellaneous small fixes and cleanups"
