Why check for CONFIG_PANEL_LGPHILIPS_LB035Q02, but not for the lcd43?
And is that even necessary? Of course it would make the kernel very
slightly smaller if you leave some code out, but otherwise does that
help? If you have the device definitions there, but the user doesn't
load the driver, they wouldn't do anything, would they?
For me the ifdefs just make the code harder to read, but I'm not sure if
there's some standard custom to have these.
