From e8f5bacfcf2ba9a98674f3cd51b63020920e16aa Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Tue, 22 Apr 2008 14:45:40 -0300 Subject: [PATCH] V4L/DVB (7308): pvrusb2: Define digital control scheme device attributes Unlike analog control, control of the digital side is not nearly as uniform among different devices. So we have to specify the correct digital control scheme as a new device attribute.
