From c8b5c505811fd4797e0ea35bcc60478d626a0971 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 30 Jul 2008 13:43:36 +0200 Subject: v4l: move BKL down to the driver level. From: Hans Verkuil 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.
