From: Antti Palosaari Date: Wed, 20 Jun 2012 01:21:34 +0000 (-0300) Subject: [media] dvb_usb_v2: merge files dvb_usb_init.c and dvb_usb_dvb.c X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=41a0abf7100928b412be4d35d62fd77c83064a9b;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git [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.
