Masahiro Yamada 4091fb95b5 scripts/spelling.txt: add "followings" pattern and fix typo instances
Fix typos and add the following to the scripts/spelling.txt:

  followings||following

While we are here, add a missing colon in the boilerplate in DT binding
documents.  The "you SoC" in allwinner,sunxi-pinctrl.txt was fixed as
well.

I reworded "as the followings:" to "as follows:" for
drivers/usb/gadget/udc/renesas_usb3.c.

Guenter Roeck e531ffc0ff hwmon: (it87) Add support for IT8792E
The chip is similar to IT8732E, but supports only three fans
and pwm outputs instead of four (the driver currently does not
support the 4th fan and pwm output of IT8732E).

Note that the chip ID is 0x8733, not 0x8792 as one would expect.

Guenter Roeck 4c7b8ca1ae hwmon: (it87) Do not overwrite bit 2..6 of pwm control registers
In IT8620E, after setting pwm control to manual, it was observed that
pwm values for fan 4..6 have reversed results (writing 0 results in fans
running at full speed, writing 255 results in fans turned off).

With the new PWM control, pwm polarity for pwm control 4..6 is specified
in its pwm control registers. Those registers are overwritten when setting
the pwm mode or the temperature mapping. Do not touch bit 2..6 of pwm
control registers on register writes to fix the problem.

not when it is enabled. Since the check is for the skip condition,
it is reversed. This applies to both IT8620 and IT8628.

Guenter Roeck 74d3b64197 hwmon: Relax name attribute validation for new APIs
While invalid name attributes are really not desirable and do mess up
libsensors, enforcing valid names has the detrimental effect of driving
users away from using the new hardware monitoring API, especially those
registering name attributes violating the ABI restrictions. Another
undesirable side effect is that this violation and the resulting error
may only be discovered some time after a conversion to the new API,
which in turn may trigger a revert of that conversion.

To solve the problem, relax validation and only issue a warning instead
of returning an error if a name attribute violating the ABI is provided.
This lets callers continue to provide invalid name attributes while
notifying them about it.

Many thanks are due to Dmitry Torokhov for the idea.

Javier Martinez Canillas bb85ceb1b3 hwmon: (ltc4151) Export OF device ID table as module aliases
The I2C core always reports a MODALIAS of the form i2c:<foo> even if the
device was registered via OF, this means that exporting the OF device ID
table device aliases in the module is not needed. But in order to change
how the core reports modaliases to user-space, it's better to export it.

Before this patch:

$ modinfo drivers/hwmon/ltc4151.ko | grep alias
alias:          i2c:ltc4151

After this patch:

$ modinfo drivers/hwmon/ltc4151.ko | grep alias

Julia Lawall 8d0ec428d5 hwmon: (w83791d) use permission-specific DEVICE_ATTR variants
Use DEVICE_ATTR_RO for read only attributes and DEVICE_ATTR_RW for
read/write attributes. This simplifies the source code, improves
readbility, and reduces the chance of inconsistencies.

The conversion was done automatically using coccinelle. It was validated
by compiling both the old and the new source code and comparing its text,
data, and bss size.
