Subject: Re: [v2] Bluetooth: hci_qca: Drop unused event during BT on

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in patchwork, it says this patch was superseded, but I can't find what its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?

Resending due to the previous reply having an empty subject, I am not sure how
that happened as the subject seemed to move into the body of the email.  Sorry
for the noise!
