Subject: hwmon: (it87) Introduce configuration field for chip suffix
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=faf392fb843007ade20720f18920f8444660cd8b;p=linux-beck.git

hwmon: (it87) Introduce configuration field for chip suffix

ITE chips may have 'E', 'F', or both 'E' and 'F' suffixes.
Introduce suffic configuration to the it87_devices structure
to simplify adding new chips.
