V4L/DVB (13839): smsdvb: add ISDB-T as DVB-T tuning support hack
Activate ISDB-T mode using module option default_mode=6. hack: use 4 lower bits in frequency for segment number [mchehab@redhat.com: fix merge conflicts and CodingStyle] Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
