3.2.65-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Imre Deak <imre.deak@xxxxxxxxx> commit 9e326f78713a4421fe11afc2ddeac07698fac131 upstream. We can call this function for a dummy console that doesn't support setting the font mapping, which will result in a null ptr BUG. So check for this case and return error for consoles w/o font mapping support.
