From d8329f8e17af85c568768fb268e0695dd1fc8148 Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Mon, 20 Feb 2012 02:33:06 -0300 Subject: [PATCH] [media] pvrusb2: Base available video standards on what hardware supports With the transition to ioctl2, the pvrusb2 driver's own standards enumeration is no longer used. Instead a generic algorithm internal to v4l is used (which is a great idea - since the pvrusb2 implementation itself was generic anyway). This change ensures that the v4l algorithm works with the correct set of hardware supported standards. This resolves a FIXME left behind from the videodev_ioctl2 transition.
