[PATCH] video: atmel_lcdfb: ensure the hardware is initialized with the correct mode

[Nicolas Ferre]

On 07/03/2014 17:20, Antoine Ténart :
> If no driver takeover the atmel_lcdfb, the lcd won't be in a working state
> since atmel_lcdfb_set_par() will never be called. Enabling a driver which does,
> like fbcon, will call the function and put atmel_lcdfb in a working state.
