I assume this should have been line 1313, right?

So does this mean that if you change the line

if (Caps.slot_type == CA_CI_LINK)

into

if (Caps.slot_type & CA_CI_LINK)

this works for you?
From the description of 'slot_type'

unsigned int slot_type;    /* OR of all supported types */

you are certainly right, but when I look at the places in the DVB driver where
'slot_type' is set:

driver/av7110/av7110.c: cap.slot_type= FW_CI_LL_SUPPORT(av7110->arm_app) ? CA_CI_LINK : CA_CI;
driver/av7110/av7110.c: cap.slot_type=CA_CI;

it doesn't look like that variable ever gets any value other that '1' (CA_CI) or
'2' (CA_CI_LINK). Therefore I wonder why this would make any change for you.
Or are you using a different/modified driver that the DVB driver from the linuxtv.org CVS?
