I see no good reason for the "If unsure, say N" advice in the description of the NVME_HWMON configuration option. It is not dangerous, it does not select any other option, and has a fairly low overhead. As the option is already not enabled by default, further suggesting hesitant users to not enable it is not useful anyway. Unlike some other options where the description alone may not be sufficient for users to make a decision, NVME_HWMON is pretty simple to grasp in my opinion, so just let the user do what they want.

The NVM Express driver is for solid state drives directly

connected to the PCI or PCI Express bus. If you know you

don't have one of these, it is safe to answer N.

To compile this driver as a module, choose M here: the
