Revision 310e3be4c2a2b9a5d2b806455e0db177ad44b6f7 authored by Andy Walls on 12 June 2010, 23:24:24 UTC, committed by Mauro Carvalho Chehab on 08 July 2010, 19:49:59 UTC
Hauppauge EEPROM tuner code 168 has recently shown up on HVR-1600 TV capture cards supported by the cx18 driver. This change allows analog tuner type autodetection to succeed for these cards. Information for decoding tuner code 168 was provided by Hauppauge. Signed-off-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
