From d56dc61265d2527a63ab5b0f03199a43cd89ca36 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 30 Jul 2008 08:43:36 -0300 Subject: V4L/DVB (8613): v4l: move BKL down to the driver level. The BKL is now moved from the video_open function in v4l2-dev.c to the various drivers. It seems about a third of the drivers already has a lock of some sort protecting the open(), another third uses video_exclusive_open (yuck!) and the last third required adding the BKL in their open function.
