From 1e4baed379a2bff3c728ea34602d3432fb047af8 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sun, 15 Jan 2006 07:52:23 -0200 Subject: [PATCH] V4L/DVB (3380): Semaphore to mutex conversion on drivers/media - Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well.
