3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: =?UTF-8?q?Antoine=20T=C3=A9nart?= <antoine.tenart@free-electrons.com>
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.
Fixes: b985172b328a (video: atmel_lcdfb: add device tree suport)
