Subject: Re: [PATCH] Bluetooth: btusb: Fix MT7925 fail to send download patch
command
Hi Peter,
kernel test robot noticed the following build errors:
[auto build test ERROR on bluetooth/master]
[also build test ERROR on bluetooth-next/master linus/master v6.7-rc7 next-20231222]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
