Hi,

I notice a bug report on Bugzilla [1]. Quoting from it:

> I have a lenovo T14S AMD Gen 3 with a *Qualcomm NFA725A* Wi-Fi card (which is actually reported by lspci as QCNFA765) and bluetooth never worked on it, failing to load the rampatch with "failed to send header" or "failed to send body" or "Failed to access otp area (-71)".

> Other people reports bluetooth as working (https://wiki.archlinux.org/title/Lenovo_ThinkPad_T14s_(AMD)_Gen_3) and a work friend has a T16 AMD gen1 which seems to have exactly the same chipset and work flowlessly. So perhaps it's an hardware issue, but I don't know how to qualify it if so.

See Bugzilla for the full thread.

FYI, this is a duplicate of his earlier report [2] that had not seen
any replies. I have added ath11k maintainers to the recipient list
so that this bug can be hopefully addressed.

Thanks.
