+Subject: fbcon: when font is freed, clear also vc_font.data
+
+From: Mika Kuoppala <mika.kuoppala@linux.intel.com>
+
+commit e6637d5427d2af9f3f33b95447bfc5347e5ccd85 upstream.
+
+commit ae1287865f5361fa138d4d3b1b6277908b54eac9
+Author: Dave Airlie <airlied@redhat.com>
+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.
