I will cook up a patch that removes the experimental status of fan control, and adds in its place an explicit toggle to enable fan control (as opposed to fan monitoring, i.e. read-only operations) as a module parameter. And it will default to "fan control is forbidden". That way, the user has to effectively tell the kernel, through the kernel command line or a module parameter, that he wants thinkpad-acpi to be capable of writing fan control information to the EC. Otherwise the driver will return -EPERM on all fan control operations, and just allow one to read fan status. What do you think? -- "One disk to rule them all, One disk to find them.
