From 017cf012570c955c3e1ff025802d7cb46fd1d37b Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Sat, 23 Sep 2006 20:40:20 -0300 Subject: V4L/DVB (5129): M920x: break out qt1010 tuner code into a separate file qt1010 is a tuner used in some other devices, so this code should be put into a separate file so that it could be reused by other drivers.
