Yi Cong posted a patch for these same two errors on October 22:

https://lore.kernel.org/linux-wireless/20261022085100.132368-1-cong.yi@linux.dev/

When the resume handshake times out, the driver already resets the card
to recover it, but still hands -110 to the PM core. The patch reports
success once that reset is scheduled. It applies cleanly to 7.2.11.
I've added Yi Cong to Cc.

Thanks for the detailed report and the unload workaround.

Devin
