Nicolas Pitre 0b0923bb6d vcs: prevent write access to vcsu devices ... commit 0c9acb1af7 upstream. Commit d21b0be246 ("vt: introduce unicode mode for /dev/vcs") guarded against using devices containing attributes as this is not yet implemented. It however failed to guard against writes to any devices as this is also unimplemented.
