Subject: Re: [PATCH v2] Bluetooth: hci_qcca: Drop unused event during BT on Hi Cheng, I have been looking into a long standing issue on the Thinkpad X13s, which has a WCN6855 where every so often would get the following error in dmesg output: Bluetooth: hci0: unexpected event for opcode 0xfc48 I don't get the message super often, 11 times since 16 April, though I do not know how many reboots happened in that time. I noticed you wrote this patch 9 months ago, and I've applied it locally and in my testing, with it applied, I cannot get the unexpected event anymore. Looking in patchwork, it says this patch was superseded, but I can't find what its replacement is. Does anyone know if this patch just fell through the cracks? -- steev
