From d782ffa24fc6ce01b3308a0bec5aa5d9d666b568 Mon Sep 17 00:00:00 2001 From: Steven Toth Date: Sat, 11 Oct 2008 12:25:25 -0300 Subject: [PATCH] V4L/DVB (9230): cx23885: MFE related OOPS fix Bug: the tree generated an oops when the cx23885 was laoded. This avoids the oops by ensuring the mutex is correctly initialised before it's used.
