openSUSE Tumbleweed: xpad kernel driver causes kernel panic

I’m using openSUSE Tumbleweed 20151214 x86_64 and kernel from Kernel:Stable repo (current version is 4.3.3-2) and sometimes when exiting from Steam, system hangs.
Journalctl shows kernel panic.
Looks like kernel panic is caused by faulty kernel diver that crashes on closing the device.
How can i contact repo maintainers?

I guess start with openSUSE bugzilla
