I applied your patch against trunk v4l-dvb tree on stock Ubuntu kernel
2.6.27-9.
While the module loads properly when passed enable_msi=1 and
/proc/interrupts as well as lspci tell me that everything should be set
up fine, I am not getting any interrupts delivered as per attached
output of:
cat /proc/interrupts
For troubleshooting purposes I have also attached the output of:
dmesg | egrep -i "tv|dvb|haupp|cx|tda"
