Hi

I think this patch is cauisng issues with older firmware

Bus 003 Device 002: ID 13d3:3563 IMC Networks Wireless_Device

[    0.315064] Bluetooth: Core ver 2.22

The correct name should be mediatek/BT_RAM_CODE_MT7961_1_2_hdr.bin

Reverting this patch fixes things

Cheers

If it helps, the device ID is 0x7961 and the fw_flavour is 24 or 0x18 in hex

Thanks for the report!

Peter, did you look into this?

Anyway: To be sure the issue doesn't fall through the cracks unnoticed,
I'm adding it to regzbot, the Linux kernel regression tracking bot:

#regzbot report:

Anyone still working on this, as that afaics did not happen -- or was
there progress and I just missed it?
