"error libnfc.driver.acr122_usb Invalid RDR_to_PC_DataBlock frame" spam

The program itself seems to work fine, but it's constantly outputting the following text making logging useless. It seems to happen every 5 seconds if a NFC tag isn't present on the reader:

If it's not possible to fix this, is it at least possible to have nfc-eventd ignore the message from libnfc so that it doesn't fill the log?

It looks like disabling all errors in libnfc itself mutes this, but would it be possible to have nfc-eventd catch these into it's own debug logging rather than having to disable it in libnfc globally on the system?
