28da9dee35 Revert "hwmon: (sch56xx-common) Add DMI override table"
This reverts commit fd2d53c367ae9983c2100ac733a834e0c79d7537.

As reported by Ian Nartowicz, this and the preceding patch
result in a failure to load the driver on Celsius W280.
While the alternative would be to add the board to the DMI
override table, it is quite likely that other systems are
also affected. Revert the offending patches to avoid future
problems.

920057ad52 hwmon: (nct6775) Fix incorrect variable reuse in fan_div calculation
In the regmap conversion in commit 4ef2774511dc ("hwmon: (nct6775)
Convert register access to regmap API") I reused the 'reg' variable
for all three register reads in the fan speed calculation loop in
nct6775_update_device(), but failed to notice that the value from the
first one (data->REG_FAN[i]) is actually used in the call to
nct6775_select_fan_div() at the end of the loop body.  Since that
patch the register value passed to nct6775_select_fan_div() has been
(conditionally) incorrectly clobbered with the value of a different
register than intended, which has in at least some cases resulted in
fan speeds being adjusted down to zero.

Fix this by using dedicated temporaries for the two intermediate
register reads instead of 'reg'.

Given that

3. "temp", "_" and the NULL terminator take 6 charactors,
fix the problem by increasing CORETEMP_NAME_LENGTH to 28.

`strncpy` is deprecated for use on NUL-terminated destination strings [1].

Let's refactor this kcalloc() + strncpy() into a kmemdup_nul() which has
more obvious behavior and is less error prone.

8046da444d hwmon: (asus_wmi_sensors) Replace deprecated strncpy() with strscpy()
`strncpy` is deprecated for use on NUL-terminated destination strings [1].

We should prefer more robust and less ambiguous string interfaces.

A suitable replacement is `strscpy` [2] due to the fact that it
guarantees NUL-termination on the destination buffer without
unnecessarily NUL-padding. If, for any reason, NUL-padding is needed
let's opt for `strscpy_pad`.

A suitable replacement is `memcpy` as we've already precisely calculated
the number of bytes to copy while `buf` has been explicitly
zero-initialized:

e7593bda6a hwmon: pmbus: Fix -EIO seen on pli1209
After doing performance optimizations the pli1209 driver failed to
probe with a probabilty of 2%. It wasn't able to read the PMBUS_OPERATION
register due to an -EIO error.

An investigation showed that the PLI1209 takes 230 usec to execute the
CLEAR_FAULTS command. During that time it's busy and NACKs all requests
on the SMBUS interface. It also NACKs reads on PMBUS_STATUS_BYTE
making it impossible to poll the BUSY flag.

Add a custom write_data function to just wait for not BUSY unconditionally
after sending a CLEAR_FAULTS command.

TEST: Verified using an I2C bus analyser that no more NACKs are seen after
      sending a CLEAR_FAULTS command.

Observing I2C traffic revealed consecutive transmission of CLEAR_FAULT
commands. While this doesn't cause issues, it extends driver probe time.

Avoid invoking pmbus_clear_fault_page for virtual registers, as they're
managed by the driver, not the chip.

The following warning is given by the Smatch static checker:

  drivers/hwmon/hp-wmi-sensors.c:1937 hp_wmi_sensors_init()
  error: uninitialized symbol 'pevents'.

If there are no instances of the HPBIOS_PlatformEvents WMI object
available, init_platform_events() never initializes this pointer,
which may then be passed to hp_wmi_debugfs_init() uninitialized.

The impact should be limited because hp_wmi_debugfs_init() uses this
pointer only if the count of HPBIOS_PlatformEvents instances is _not_
zero, while conversely, it will be uninitialized only if the count of
such instances _is_ zero. However, passing it uninitialized still
constitutes a bug.

45f154dc96 hwmon: (pmbus/mp2975) Add OCP limit
Add support for PMBUS_IOUT_OC_FAULT_LIMIT.
Add a helper function to convert the limit to LINEAR11 format
and read data->info.phases[0] on MP2971 and MP2973 as well.

5239277ef4 hwmon: (pmbus/mp2975) Add support for MP2971 and MP2973
Add support for MP2971 and MP2973, the successor of MP2975.

The major differences are:
 - On MP2973 and MP2971 the Vref cannot be read and thus most of
   the OVP/current calculations won't work.
 - MP2973 and MP2971 also support LINEAR format for VOUT
 - MP2973 and MP2971 do not support OVP2
 - On MP2973 and MP2971 most registers are in LINEAR format
 - The IMVP9_EN bit has a different position
 - Per phase current sense haven't been implemented.

As on MP2975 most of the FAULT_LIMIT and WARN_LIMIT registers
have been redefined and doesn't provide the functionality as
defined in PMBUS spec.

Tested on MP2973 and MP2971.
