From 231be4e92cc0398781e6acda0e3f8ea54a7fa10f Mon Sep 17 00:00:00 2001 From: Adam Baker Date: Sun, 10 Feb 2008 22:48:19 +0100 Subject: [PATCH] rt2x00: correct address calc for queue private data When calculating the offset to add to the queue entry base to get the individual entry's private data area the base address must be treated as a char * not a struct queue_entry so we can do byte oriented pointer arithmetic with it.
