Patches 1 and 2 look fine (I'd rather have the micrometers too).
I have more concerns about this one.
My main issue is that this patch both reshuffle existing parts and add
new features, which makes it hard to review.

The conversion input_report_rel(... REL_WHEEL,...) to
hid_scroll_counter_handle_scroll() should be dealt in a separate
patch.

You are using usage_table to force the .event function to be called
only on the WHEEL events. This is correct, but I have a feeling this
will be harder to understand when we are going to extend the .event()
function for other events.
If you rather keep the cde that way, please add a comment at the
beginning of the function stating that we are only called against
WHEEL events because of usage_table.
