Yes, I have tested this code with my LCD module and it works
as before. This is what I've emphasized in the cover letter -
- I made sure (and tested), that all lcd and keypad params are
set to the same state as before this patch series, and that
the current behaviour of the module doesn't change. I've tested
all profile/lcd_type combinations in an automated way to catch
any edge cases :)

Thanks,
Mariusz
