Subject: fbcon: when font is freed, clear also vc_font.data
From: Mika Kuoppala <[email protected]>
commit e6637d5427d2af9f3f33b95447bfc5347e5ccd85 upstream.
commit ae1287865f5361fa138d4d3b1b6277908b54eac9
Author: Dave Airlie <[email protected]>
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.
