[PATCH RESEND 6/8] fbdev: vesafb: bind to platform-framebuffer device

From: David Herrmann
Date: Fri Aug 02 2013 - 08:06:47 EST


x86 creates platform-framebuffer platform devices for every system
framebuffer. Use these instead of creating a dummy device.

This requires us to remove the __init annotations as hotplugging may occur
during runtime.
