4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Nicolas Pitre <nicolas.pitre@xxxxxxxxxx> 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.
