Subject: media: dvb-usb-cxusb: Geniatech T230C support
Author:  Evgeny Plehov <evgenyple...@ukr.net>
Date:    Tue Jan 9 18:33:38 2018 -0500

This reverts commit f8585ce655e9cdeabc38e8e2580b05735110e4a5.

The T230C is handled by the dvb-usb-v2/dvbsky.c driver, which should
be preferred over a dvb-usb (v1) driver.
