From cd5de26288604cb8a6f7fba041cc5fb610cbff9e Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 1 Apr 2013 18:04:21 -0300 Subject: [media] pwc: Fix comment wrt lock ordering With all the changes to handle the locking in the v4l2-core rather then at the driver level, the order in which the 2 pwc locks need to be taken has changed, update the comment in the header file to correctly reflect this.
