"proc_thermal 0000:00:04.0: Unsupported event [0x84]" flooding log

My system log is flooded with the following message:

kernel: proc_thermal 0000:00:04.0: Unsupported event [0x84]

dmesg:

...
and so on

Any idea what that means? Since everything seems to work fine, I'm wondering if there's a way to prevent this specific event to be logged, since it's making the log unusable.

I'm running the latest linux kernel, but it's the same with the linux-lts package.

Not sure what other information might be useful.

I also have these on my Asus UX303LB and was wondering if you have similar machine and these logs refer to particular device
