Subject: [PATCH] region changes for rocket

Hi
this is a small patch for Rocketport device driver for Linux to
1) remove two calls to check_region using request_region instead
2) release allocated region resource in case of error.
I don't have this hardware so compilation checked only.
This patch does not remove all references to check_region in this driver (one \
reference still left unchanged).
Patch also available at the following URL:

Comments and suggestions welcome
