Subject: [PATCH] console/dummy: leave .con_font_get set to NULL
Git-commit: 724ba8b30b044aa0d94b1cd374fc15806cdd6f18
Patch-mainline: v4.16-rc1
References: bsc#1051510

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.
