Hi there!
The attached patch a PHYS-string and a connection to the relevant pci-device
to let udev now this and create more user-friendly/persistent links on the
event-device. Code with some changes taken from budget-ci.c
With that patch, udev-103 creates:
/dev/input/by-path/pci-0000\:00\:0a.0--event-ir
Nevertheless input-handling for av7110 needs some changes: one can for example
only use input-connector of first card.
Other possible (simpler) change: Change name of input device and attach name
of dvb-device.
Greetings
Matthias

Add PHYS-string to help udev and
others using EVIOCPHYS ioctl to
identify the input device node.
