[PATCH 3.16 130/410] console/dummy: leave .con_font_get set to NULL

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.16.57-rc1 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.
