[PATCH] dvb_usb_dvbsky: Mygica T230C2 add support for T230C hw version 2

[JP <jp@xxxxxxx>]

I made the Mygica T230c2 work on kernel 5.1.7, but I have no idea

how to submit this. http://jpvw.nl/pub/test/dvb/linux-5.1.7-t230c2.patch


Please can someone help me out. It looks like the extra code in the

demodulator does not effect other drivers that use it. Tested with a

T230, they bothseem to work OK.
