[patch 2.6.27.y 1/6] firewire: fix setting tag and sy in isotransmission

[Stefan Richter]

Date: Fri, 12 Sep 2008 18:09:55 +0200 (CEST)
From: Stefan Richter <stefanr@xxxxxxxxxxxxxxxxx>

Reported by Jay Fenlason:
The iso packet control accessors in fw-cdev.c had bogus masks.

Same as commit 7a1003449c693f0d57443c8786bbf19717921ae0.
