Looks like si2168 firmware failed to download, but si2157 succeeded.
Could you add some more time for driver timeout? Current timeout is
selected by trial and error, lets say it takes always max 43ms for my
device I coded it 50ms.
drivers/media/dvb-frontends/si2168.c
/* wait cmd execution terminate */
#define TIMEOUT 50
change it to
#define TIMEOUT 500
Also, if it does not work, could you enable debugs to see what happens?
rmmod si2168
modprobe si2168
echo -n 'module si2168 =pft' > /sys/kernel/debug/dynamic_debug/control

Antti
