From ddee56943ab6df098e411fe943c2a52063fba0a5 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Fri, 15 Jun 2012 21:17:04 -0300 Subject: [PATCH] [media] dvb_usb_v2: .read_mac_address() callback changes Give DVB adapter as a parameter for callback. MAC address is adapter property and it could be (at least in theory) there is devices having multiple adapters and all has own MAC. Also add error handling. If callback fails error is returned which leads device unregister.
