From 042671040db95a896c5ca960b9b656692a787892 Mon Sep 17 00:00:00 2001 From: Ivo van Doorn Date: Sun, 6 Jan 2008 23:39:25 +0100 Subject: [PATCH] rt2x00: Store queue idx and entry idx in data_ring and data_entry Store the queue idx inside structure data_ring Store the entry idx inside structure data_entry This saves us a few calls to ARRAY_INDEX() which is now unused.
