From e6637d5427d2af9f3f33b95447bfc5347e5ccd85 Mon Sep 17 00:00:00 2001 From: Mika Kuoppala Date: Mon, 22 Apr 2013 14:19:26 +0300 Subject: [PATCH] fbcon: when font is freed, clear also vc_font.data commit ae1287865f5361fa138d4d3b1b6277908b54eac9 Author: Dave Airlie Date: Thu Jan 24 16:12:41 2013 +1000 fbcon: don't lose the console font across generic->chip driver switch uses a pointer in vc->vc_font.data to load font into the new driver. However if the font is actually freed, we need to clear the data so that we don't reload font from dangling pointer.
