Latest commit cfbd950 Oct 20, 2016 @linusw linusw committed with tomba video: ARM CLCD: fix Vexpress regression
The CLCD does not come up on Versatile Express as it does not
(currently) have a syscon node for controlling the block apart
from the CLCD itself. Make sure the .init() function can bail
out without an error making it probe again.
