[PATCH] Export new char dev functions

From: Jonathan Corbet <corbet@lwn.net>

Nobody told me that the failure to export these (like their block
counterparts) was anything but an oversight; modules will not be able to
use larger device numbers without them.  So...this patch exports the new
char device functions.
