Created attachment 301617 [details] [review]
backend: Apply the right settings to the right input devices

Since 8769b3d55, the checks performed on which update_* function was
called for each device got quite more lax, leading to failed asserts
on code that assumed the previous behavior.

Change update_[mouse|touchpad|trackball]_* to bail out early if the
device received has not the right type, and remove the asserts.
