(udev-worker)[348]: nvidia: Process

Hello,
I get the following errors, but apparently everything works.
Does anyone know what to do with this?

Aug 30 15:23:50 I-NET (udev-worker)[348]: nvidia: Process '/usr/bin/bash -c '/usr/bin/mknod -Z -m 666 /dev/nvidiactl c $(grep nvidia-frontend /proc/devices | cut -d \  -f 1) 255'' failed with exit code 1.
Aug 30 15:23:50 I-NET (udev-worker)[348]: nvidia: Process '/usr/bin/bash -c 'for i in $(cat /proc/driver/nvidia/gpus/*/information | grep Minor | cut -d \  -f 4); do /usr/bin/mknod -Z -m 666 /dev/nvidia${i} c $(grep nvidia-frontend /proc/devices | cut -d \  -f 1) ${i}; done'' failed with exit code 1.

Is it not possible to rewrite the rule so that the rule is terminated if the files are present?
