Dmitry Torokhov 54bf08946a Input: synaptics-rmi4 - when registering sensors do not call them "drivers"
We are not registering drivers, but transport devices (AKA sensors), so
let's call them that.

Also let's rename "retval" to "error" in probe() functions as the variables
are used to store error codes.

elements at once.

The mapping table holds address in LE form, so we should convert it
to CPU when comparing it.
