[v2,1/2] hwmon: (nct6775) Fix incomplete register array
Commit Message
From: Xing Tong Wu <xingtong.wu@siemens.com>
The nct6116 specification actually includes 5 PWMs, but only 3
PWMs are present in the array. To address this, the missing 2
PWMs have been added to the array.

No, this isn't correct. Chapter 8.4.4 in the datasheet says that auxfanout1 and
auxfanout2 are always in pwm mode, so those register addresses and bit positions
need to be 0 in the array. Also, please just extend the NCT6106 arrays.

Please just extend the nct6106 array.
Thanks,

Please rephrase.
The subject and the description is a bit misleading. The need to extend
the arrays is necessary, but the key change is adding support for the two
additional fan controls.
Thanks,
