[2.6 patch] prism54: make some functions static

To: Margit Schubert-While <margitsw@xxxxxxxxxxx>
Subject: [2.6 patch] prism54: make some functions static
From: Adrian Bunk <bunk@xxxxxxxxx>
Date: Sat, 30 Oct 2004 07:45:34 +0200
Cc: prism54-private@xxxxxxxxxxx, netdev@xxxxxxxxxxx, jgarzik@xxxxxxxxx, linux-net@xxxxxxxxxxxxxxx, linux-kernel@xxxxxxxxxxxxxxx
Sender: netdev-bounce@xxxxxxxxxxx
User-agent: Mutt/1.5.6+20040907i
the patch below makes some functions in prism54 that are only required 
locally static.

As a side effect it turned out that the mgt_unlatch_all function was 
completely unused, and I've therefore removed it.

I also considered moving display_buffer as static inline into 
islpci_mgt.h, but I wasn't 100% sure and therefore left it.
