This is a kernel issue, and you might need to get in touch with the
kernel devs or (sometimes easier) downstream distro kernel maintainers.
As I said, this is above may $0 paygrade...

yup, looks fine if you plan to use the /dev/lirc0 device and the default
driver.
Basically this looks like a kernel bug to me: It has a rc0 /sys device,
runs the lirc protocol and still does not present a /dev/lirc0 link. I
assume you have checked dmesg for any clue.
FWIW, a working lirc0 also creates a /sys/class/rc/rc0/lirc0 link.
Cheers!
