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

From: Nicolas Pitre nicolas.pitre@linaro.org
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.
