Module fails on Kernel 4.15

[lstein]

Module was working perfectly on Mint 18.3 with kernel 4.10. Recently upgraded to Mint 19.1 and kernel 4.15, and module is broken. "cat /proc/acpi/nuc_led" gives a kernel log error of "Unable to get NUC power LED state" followed by a similar message for the ring. Attempting to set the state gives a kernel log error of "Unable to set NUC LED state: WMI call failed."

I'm using the module on NUC6CAYH with 4.19 without any problem.
