From: Antoine Ténart <[email protected]> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== commit 7d3477d801808a5037a511cf5a5aae5718e7ecce upstream. 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.
