V4L/DVB (9010): Add support for SDMC DM1105 PCI chip
Add support for SDMC DM1105 PCI chip. There is a lot of cards based on it, like DvbWorld 2002 DVB-S , 2004 DVB-S2 Signed-off-by: Igor M. Liplianin <liplianin@me.by> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

7 Support for cards based on the SDMC DM1105 PCI chip like
8 DvbWorld 2002
9
10 Since these cards have no MPEG decoder onboard, they transmit
11 only compressed MPEG data over the PCI bus, so you need
12 an external software decoder to watch TV on your computer.
13
14 Say Y or M if you own such a device and want to use it.
