Mounting USB hard drive - error registering v4l2 subdevice

While that is an error it does not matter at all and does not prevent your board from booting. It just tells you that you do not have a camera connected on the camera port or something. It is a good idea to disable the camera driver if you do not use it:

Code:

cat <<EOF | sudo tee -a /etc/modprobe.d/blacklist-pine64.conf
blacklist vfe_v4l2
blacklist vfe_io
EOF
