It seems my TC980Cs have Si2168-A30's on board

[  118.526665] si2168 8-0064: found a 'Silicon Labs Si2168-A30'
[  118.640642] si2168 8-0064: downloading firmware from file 'dvb-
demod-si2168-a30-01.fw'
[  121.762983] si2168 8-0064: firmware version: 3.0.16

dvbv5_scan does not work me.
sha1sum for this firmware is:
59a0b90703d65229fb2589b52834ca68d1e96ad9  dvb-demod-si2168-a30-01.fw
