From 2e5155ecbb729d3a2e7d1cea7c18493516fec55a Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Fri, 2 Aug 2013 14:05:25 +0200 Subject: [PATCH] fbdev: vesafb: bind to platform-framebuffer device 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.
