While this is nice overall, I think you just found a bug in the driver.

Why is this a static variable?  That means this affects all devices that
this driver touches, which seems very wrong, right?

So shouldn't tm_trigger be a per-device attribute?

It also should be a boolean, right?

Can you fix this up to be a per-device attribute instead?
