From c6d26cfe26e475c9ddd09667dd6694b34469f4dc Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 20 Feb 2012 02:21:00 -0300 Subject: [PATCH] [media] pvrusb2: convert to video_ioctl2 Note: there is one FIXME remaining: the tvnorms field of struct video_device should be set up correctly. I have used V4L2_STD_ALL for now, but I'm sure this can be improved. This field is used by video_ioctl2 to implement ENUMSTD.
