From 41a0abf7100928b412be4d35d62fd77c83064a9b Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Tue, 19 Jun 2012 22:21:34 -0300 Subject: [PATCH] [media] dvb_usb_v2: merge files dvb_usb_init.c and dvb_usb_dvb.c Merge files dvb_usb_init.c and dvb_usb_dvb.c to dvb_usb_core.c. It is still under 1000 lines of code after all the optimization so put it one file.
