Subject: [PATCH] Fix Alsa issues including Oopses with OSS emulation

From: Benjamin Herrenschmidt <[email-masked]>
Date: Wed, 22 Dec 2004 19:13:13 +0100

This patch (which will be send upstream separately by the Alsa folks) fixes
an signed vs. unsigned char problem in Alsa which was the cause of the Oops
people were experiencing on ppc with OSS emulation and possibly other issues.
