The convention is to use the stock ticker, capitalized, if a company
has one, I guess dallas is MXIM these days, but dallas is a good
substitute based on the fact that most people still remember Dallas
clock chips and so on from the Ancient Days. STMicroelectronics is STM.
I couldn't care less about case sensitivity, but the stock ticker
thing was always a good idea.. it gives a sort of grounding in reality
for the manufacturer names.

Are we still following this convention or are the names of devices
simply arbitrarily defined by Linux kernel developers now?
