Hi all,

After merging the hwmon-staging tree, today's linux-next build (powerpc
allyesconfig) failed like this:

Probably caused by commit

a2105efee6e7 ("hwmon: (nct6775) Split core and platform driver")

I have reverted that commit for today - and the following commits

4dcbcf34a249 ("hwmon: (nct6775) add ASUS PRO H410T / PRIME H410M-R / ROG X570-E GAMING WIFI II")
58f1d9ebfce6 ("hwmon: (nct6775) Add i2c driver")
