From 1a60d4c5a0c4028559585a74e48593b16e1ca9b2 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 16 Jan 2006 16:29:08 +0100 Subject: [ALSA] semaphore -> mutex (core part) Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well.
