Wow! I don't understand how this managed to slip through the various
tests for that long. That code is the the same in my 2.4 driver too,
so that means it has never worked for the last 5 years !

Obvious ACK from me, but please take a quick look at the place
where this define is used to ensure that any expected setting of
CONFIG_PANEL_LCD_CHARSET will not result in some other cryptic
error messages being sent to the user.

Thanks!
