[media] saa7134: switch tuner FMD1216ME_MK3 to analog
The tuner FMD1216ME_MK3 suffers the same problem as FMD1216MEX_MK3, as described in saa7134-cards.c (disabled IF, enabled DVB-T). The card does work under MS Windows, after soft reboot into Linux it continues to work, only then tda9887 is loaded as well. I copied the relevant code from the BEHOLD_H6 section to MD7134. The CTX946 TV card doesn't detect a signal after cold boot, seems Signed-off-by: Juergen Gier <juergen.gier@gmx.de> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
