The return path can be improved by returning upon first failure. The
current implementation would try to register the second interrupt even
if the first one failed, which is unnecessary.
Moreover, if no irqs are available, the return value should be zero
(the driver supports the use case with no interrupts). Currently the
initial value is unassigned and that may lead to returning an unknown
value if stack variables are not automatically set to zero and no irqs
were provided.

The reg_val variable in cc2_get_reg_val() might be used without a known
value if cc2_read_reg() fails. That leads to a useless data conversion
because the returned error means the read operation failed and the data is
not relevant.
That makes its initial value irrelevant as well, so skip the data
conversion instead. If no error happens, a value is assigned to reg_val
and the data conversion is required.

The total memory needed for saving per core temperature data depends on
the number of cores in a package. Using static allocated memory wastes
memories on systems with low per package core count.
Improve the code to use dynamic allocated memory so that it can be
improved further when per package core count information becomes
available.
No functional change intended.

This driver exposes hardware sensors of the ASUS ROG RYUJIN II 360
all-in-one CPU liquid cooler, which communicates through a proprietary
USB HID protocol. Report offsets were initially discovered in [1] by
Florian Freudiger.
Available sensors are pump, internal and external
(controller) fan speed in RPM, their duties in PWM, as well as
coolant temperature.
Attaching external fans to the controller is optional and allows them
to be controlled from the device. If not connected, the fan-related
sensors will report zeroes. The controller is a separate hardware unit
that comes bundled with the AIO and connects to it to allow fan control.
The addressable LCD screen is not supported in this
driver and should be controlled through userspace tools.

This driver enables hardware monitoring support for NZXT Kraken
X53/X63/X73 and Z53/Z63/Z73 all-in-one CPU liquid coolers.
All models expose liquid temperature and pump speed (in RPM), as well as
PWM control (natively only through a temp-PWM curve, but the driver also
emulates fixed PWM control on top of that). The Z-series models
additionally expose the speed and duty of an optionally connected fan,
with the same PWM control capabilities.
Pump and fan duty control mode can be set through pwm[1-2]_enable,
where 1 is for the manual control mode and 2 is for the liquid temp
to PWM curve mode. Writing a 0 disables control of the channel through
the driver after setting its duty to 100%. As it is not possible to query
the device for the active mode, the driver keeps track of it.
The temperature of the curves relates to the fixed [20-59] C range, per
device limitations, and correlating to the detected liquid temperature.
Only PWM values (ranging from 0-255) can be set.
The addressable RGB LEDs and LCD screen, included only on Z-series models,
are not supported in this driver.

The Amphenol ChipCap 2 is a capacitive polymer humidity and temperature
sensor with an integrated EEPROM and minimum/maximum humidity alarms.
All device variants offer an I2C interface and depending on the part
number, two different output modes:
- CC2D: digital output
- CC2A: analog (PDM) output
This driver adds support for the digital variant (CC2D part numbers),
which includes the following part numbers:
- non-sleep measurement mode (CC2D23, CC2D25, CC2D33, CC2D35)
- sleep measurement mode (CC2D23S, CC2D25S, CC2D33S, CC2D35S)
The Chipcap 2 EEPROM can be accessed to configure a series of parameters
like the minimum/maximum humidity alarm threshold and hysteresis. The
EEPROM is only accessible in the command window after a power-on reset.
The default window lasts 10 ms if no Start_CM command is sent. After the
command window is finished (either after the mentioned timeout of after
a Start_NOM command is sent), the device enters the normal operation
mode and makes a first measurement automatically.
Unfortunately, the device does not provide any hardware or software
reset and therefore the driver must trigger power cycles to enter the
command mode. A dedicated, external regulator is required for that.
This driver keeps the device off until a measurement or access to the
EEPROM is required, making use of the first automatic measurement to
avoid different code paths for sleep and non-sleep devices.
The minimum and maximum humidity alarms are configured with two
registers per alarm: one stores the alarm threshold and the other one
keeps the value that turns off the alarm. The alarm signals are only
updated when a measurement is carried out.

Class-based I2C probing requires detect() and address_list both
to be set in the I2C client driver, see checks in i2c_detect().
It's misleading to declare I2C_CLASS_HWMON support if the driver
doesn't implement detect().
Class-based probing is a legacy mechanism, in addition apparently
nobody ever noticed that class-based probing has been non-functional
in both drivers from the very beginning. So drop the fragments of

const struct hwmon_channel_info *. However, without explicit const,
HWMON_CHANNEL_INFO() creates mutable compound literals, and the const
pointers point at the mutable data. Add const to place the data in
rodata.

- Make sure a warning is issued when a hrtimer gets queued after the

will get ignored

Pull x86 fixes from Borislav Petkov:
- Correct the minimum CPU family for Transmeta Crusoe in Kconfig so
that such hw can boot again
- Do not take into accout XSTATE buffer size info supplied by userspace
when constructing a sigreturn frame
- Switch get_/put_user* to EX_TYPE_UACCESS exception handling when an
MCE is encountered so that it can be properly recovered from instead
of simply panicking
* tag 'x86_urgent_for_v6.8_rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/Kconfig: Transmeta Crusoe is CPU family 5, not 6
x86/fpu: Stop relying on userspace for info to fault in xsave buffer
x86/lib: Revert to _ASM_EXTABLE_UA() for {get,put}_user() fixups
