[PATCH 5/5] hwmon: (nct6683) Enable pwm control on ASRock B850 Steel Legend WiFi

From: Johan Dahlin

Date: Tue Aug 25 2026 - 05:27:55 EST


Fan control has been measured on this board: with a fan in manual mode the
applied pwm value tracks what is written, and the fan responds
proportionally from 337 RPM at pwm 60 to 933 RPM at pwm 255.

Allow pwm writes on this board.
