Public bug reported:
Current setup/failing setup:
Linux frontend01 4.13.0-17-generic #20-Ubuntu SMP Mon Nov 6 10:04:08 UTC 2017
x86_64 x86_64 x86_64 GNU/Linux
Ubuntu 4.13.0-17.20-generic 4.13.8
Ubuntu 17.10, 4.13.0-17-generic
Nuvoton w836x7hg Infrared Remote Transceiver
Zotac ID42
Working setup:
Ubuntu 17.10, 4.4.8-040408-generic
I'm not able to get the remote working after a normal reboot (using 4.13 kernel)
It does actually after a suspend and wake-up, and do a echo 'auto' to resources.
Please find snapshot of dmesg below:

In order to get the device working I need the following in this order:
* suspend/resume
* echo "auto" > /sys/bus/acpi/devices/NTN0530\:00/physical_node/resources
