From 3593cab5d62c4c7abced1076710f9bc2d8847433 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Tue, 7 Feb 2006 06:49:14 -0200 Subject: V4L/DVB (3318b): sem2mutex: drivers/media/, #2 Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well.
