No, I just forgot to remove it from the series settings, so you can consider it as final. I had one minor question in my head (but that's mostly for patches 3 and 4): in linux-firmware we will have ath10k/WCN3990/hw1.0/qcm2290 and make qrb4210 as a symlink to it. Is that fine from your POV? Or should we use sensible device names (e.g. qcom-rb1)? -- With best wishes Dmitry
