Subject: failed to remove key (0, ce:ce:1e:27:bb:e0) from hardware (-110)
 (ETIMEDOUT)

Dear Linux folks,


Linux 6.11-rc6+ logged the warning below when resuming from ACPI S3 (or 
unloading and loading the `ath10k_core`/`ath10k_pci` modules) having 
been connected to an AVM network:

     wlp58s0: failed to remove key (0, ce:ce:1e:27:bb:e0) from hardware 
(-110)

Error code 110 is the value for ETIMEDOUT. I saw James patch [1], and 
applied it, and the error is still there (as exepected).

Can the warning be improved so the user know, which component is at fault?


Kind regards,

Paul
