Hello, I made another effort to convert the w83781d to new-style binding. The series consists of the following two patches: [PATCH 1/2] hwmon: w83781d: make ISA interface depend on CONFIG_ISA [PATCH 2/2] hwmon: w83781d: use new style driver binding I have tested it one a PowerPC MPC8544 board. I did not have any occasion to verify the ISA related part. Wolfgang.
