drm/i915: Kick fbdev before vgacon
It's magic, but it seems to work. This fixes a regression introduced in commit 1bb9e632a0aeee1121e652ee4dc80e5e6f14bcd2 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Jul 8 10:02:43 2014 +0200 drm/i915: Only unbind vgacon, not other console drivers My best guess is that the vga fbdev driver falls over if we rip out parts of vgacon. Hooray.
