From 6a540254966f8a01de0f7c78a27db17458c2d8f5 Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Sun, 2 Dec 2007 23:51:34 -0300 Subject: [PATCH] V4L/DVB (6705): pvrusb2: Implement default standard selection based on device type This adds a default video standard setting to the pvr2_device_desc structure for describing device types. With this change it is possible to set a reasonable default standard based on device type.
