From 6740a932882f43056b8545e5b0b85511975d0a7c Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 30 Nov 2011 14:54:05 -0300 Subject: [PATCH] [media] tm6000: automatically load alsa and dvb modules All devices should support alsa module. Devices with DVB will auto-load the dvb module. This way, tm6000-based devices should now have hot plugin.
