Is there a difference between the 'acer-wmi' and 'acer_wmi' drivers?

Question

Is there a difference between drivers acer-wmi, and acer_wmi?

Sometimes on my computer I see the driver acer-wmi and acer_wmi, they are also both quoted in forums interchangeably.

Answer 1

There is no difference.

acer-wmi.ko is the name of the module (driver) file, while the actual module, following Linux naming conventions, is called acer_wmi.

References in forums, blogs, etc. may use both conventions. Kernel logs, etc. should use acer_wmi.
