Date: Sun, 26 Jun 2011 13:06:04 -0300 From: Mauro Carvalho Chehab <mchehab@...hat.com> To: unlisted-recipients:; (no To-header on input) Cc: Linux Media Mailing List <linux-media@...r.kernel.org>, LKML <linux-kernel@...r.kernel.org> Subject: [PATCH 03/14] [media] v4l2-ioctl: Add a default value for kernel version Most drivers don't increase kernel versions as newer features are added or bug fixes are solved. So, vidioc_querycap returned value for cap->version is meaningless. Instead of keeping this situation forever, let's add a default value matching the current Linux version. Drivers that want to keep their own version control can still do it, as they can override the default value for cap->version.
