commit 9c62e2282900332c8b711d9f9e37af369a8ef71b upstream. The Linux hwmon sysfs API values for pwmX_auto_pointY_pwm represent an integer value between 0 (0%) to 255 (100%) and the pwmX_auto_pointY_temp represent millidegrees Celcius. Commita6d80df47e("hwmon: (gsc-hwmon) fix fan pwm temperature scaling") properly addressed the incorrect scaling in the pwm_auto_point_temp_store implementation but erroneously scaled the pwm_auto_point_pwm_show (pwm value) instead of the pwm_auto_point_temp_show (temp value) resulting in: # cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_pwm 25500 # cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_temp 4500 Fix the scaling of these attributes: # cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_pwm 255 # cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_temp 45000 Fixes:a6d80df47e("hwmon: (gsc-hwmon) fix fan pwm temperature scaling") Cc: stable@vger.kernel.org Signed-off-by: Tim Harvey <tharvey@gateworks.com> Link: https://lore.kernel.org/r/20250718200259.1840792-1-tharvey@gateworks.com Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
