From a3dfc6d925ca1bbd1a228253acb93f08657bad25 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 13 Feb 2015 10:08:17 -0300 Subject: [PATCH] [media] dvb-usb: create one media_dev per adapter Instead of assuming just one adapter, change the code to store one media controller per adapter. This works fine for dvb-usb, as, on all drivers here, it is not possible to write a media graph that would mix resources between the two different adapters.
