Series | [v1] Bluetooth: btusb: Add support different nvm to distinguish different factory for WCN6855 controller | expand |
Hi Zijun, > we have different factory to produce wcn6855 soc chip, so we should use > different nvm file with surfix to distinguish them.

I am pretty sure there will be another factory at some point and then this code becomes too complex. Check if you could use a table for this. Regards Marcel
