Subject: [PATCH RESEND 8/8] fbdev: fbcon: select VT_HW_CONSOLE_BINDING
Date: Fri, 2 Aug 2013 14:05:27 +0200 [thread overview]
Message-ID: <1375445127-15480-9-git-send-email-dh.herrmann@gmail.com> (raw)
In-Reply-To: <1375445127-15480-1-git-send-email-dh.herrmann@gmail.com>
fbdev provides framebuffer hotplugging, hence, we need to allow fbcon to
unbind from framebuffers. Unfortunately, fbcon_fb_unbind() cannot unbind
from the last framebuffer, unless console-unbinding is supported.
Fixing fbcon_unbind() to return 0 caused some horrible NULL-derefs in the
VT layer and I couldn't figure out why. Hence, lets just require
console-unbinding so fbdev hotplugging works with fbcon.
