[PATCH v1] Bluetooth: btusb: Add support different nvm to distinguish different factory for WCN6855 controller

From: Zijun Hu
Date: Wed Aug 04 2021 - 06:05:00 EST


From: Tim Jiang <tjiang@xxxxxxxxxxxxxx>

we have different factory to produce wcn6855 soc chip, so we should use
different nvm file with surfix to distinguish them.
