> | [ 38.138881] Bluetooth: hci0: RTL: firmware file rtl_bt/rtl8761cu_fw not found
The stable code matches mainline. The failure is a missing firmware file:
rtl_bt/rtl8761cu_fw.bin has been in linux-firmware only since 20251111,
and Debian trixie's firmware-realtek 20250410-2 does not have it.
Marcel, Luiz: could you, or Christoph Zwerschke as the author of the ID
commit, send an upstream revert, or a fallback to ROM firmware when
rtl8761cu_fw.bin is missing? Stable will take it for 7.2, 6.18 and 6.12
through the normal Cc: stable route once it is in mainline.
