From b52e7c768724bde20669f37f37290922de348151 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sat, 23 Jul 2011 12:16:26 -0300 Subject: [PATCH] [media] mt2063: add some useful info for the dvb callback calls The per-delivery system tables are confusing. Add an extra table that explains them, and some dprintk calls, that allows to check if mt2063 driver is working as expected.
