Subject: [PATCH] vt: remove VT_RESIZE and VT_RESIZEX from vt_compat_ioctl()
From: Nicolas Pitre <npitre@...libre.com>

They are listed amon those cmd values that "treat 'arg' as an integer"
which is wrong. They should instead fall into the default case. Probably
nobody ever exercized that code since 2009 but still.

Fixes: e92166517e3c ("tty: handle VT specific compat ioctls in vt driver")
