Subject[PATCH] HiSax telespci: convert to PCI hotplug API

commit 6a95b63013e6bdd316dca39053174cb1add4b555
Author: Jeff Garzik <jeff@garzik.org>
Date: Mon Jul 16 03:49:25 2007 -0400

[ISDN] HiSax: convert telespci to PCI hotplug API

Also, some exports needed now that arocfi and hscx are being picked up
via libhisax.

[like other patches, the non-telespci changes in this patch need to
be moved earlier in the patch series, before pushing upstream -jg]
