From 44e3e173c354122e79ef8b707ae6caa179bb1da4 Mon Sep 17 00:00:00 2001
From: Thomas Gleixner <tglx@linutronix.de>
Date: Sun, 26 Jul 2009 00:25:18 +0200
Subject: [PATCH] drivers/macintosh/adb: Do not claim that the semaphore is a mutex
commit 9b499baa6a91c12360b69b0402171d760c2b6eb5 in tip.
The usage of this "mutex" is non obvious and used as completion in
some places. Make it a semaphore.
