From: Hans Verkuil Date: Sun, 9 Sep 2012 12:03:29 +0000 (-0300) Subject: [media] bttv: fix querycap and radio v4l2-compliance issues X-Git-Tag: Ubuntu-5.0.0-8.9~13035^2~1325 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=78dea1aed44a6e3e16973e584b00825359d470bd;p=mirror_ubuntu-disco-kernel.git [media] bttv: fix querycap and radio v4l2-compliance issues The querycap ioctl didn't support V4L2_CAP_DEVICE_CAPS and the radio device implemented audio and video inputs and s_std, which are not part of the radio API.
