[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

From: Nicolas Pitre 

commit 724ba8b30b044aa0d94b1cd374fc15806cdd6f18 upstream.

When this method is set, the caller expects struct console_font fields
to be properly initialized when it returns. Leave it unset otherwise
nonsensical (leaked kernel stack) values are returned to user space.
