Subject: Re: [PATCH v6] Bluetooth: btusb: Add support using different nvm for
variant WCN6855 controller
Hi Zijun,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on bluetooth-next/master]
[also build test ERROR on linus/master v5.14-rc7 next-20210827]
[cannot apply to linux/master bluetooth/master]
[If your patch is applied to the wrong git tree, kindly drop us a note.
