Subject: [PATCH v1] Bluetooth: btusb: Add support different nvm to distinguish different factory for WCN6855 controller
Date: Wed,  4 Aug 2021 18:04:27 +0800	[thread overview]
Message-ID: <1628071467-27190-1-git-send-email-zijuhu@codeaurora.org> (raw)

From: Tim Jiang <tjiang@codeaurora.org>

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