From 62932df8fb20ba2fb53a95fa52445eba22e821fe Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 16 Jan 2006 16:34:20 +0100 Subject: [ALSA] semaphore -> mutex (PCI part) Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well.
