Ok, I see. It's still confusing because it's different from how other
drivers handle this (case in point: I was very confused by this). 

Do you see any downsides in changing the code to consistently annotate
the eeprom as either __le or __be (whichever is more common), using
the respective endianess accessors, and then doing the swap if the
data we read is the opposite way?
