From fb62a5953e9e6969f78adc7291c1a8845116f776 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 31 Jan 2008 13:59:29 -0300 Subject: V4L/DVB (7122): saa7134-empress: Remove back lock videobuf functions at close() method already locks videobuf. It makes no sense to keep the locking at empress close() method. There is also a lock at open() method. I'm not sure if it is safe to remove the locking there.
