> [v6.19-rc1]The stable trees match mainline here, so nothing is going into stable for this. The fix has to come from the Bluetooth maintainers or Christoph: an upstream revert of the ID commits, or a fallback to the ROM firmware when rtl8761cu_fw.bin is missing. Stable will take either one for 7.2, 6.18 and 6.12 through the normal Cc: stable route once it is in mainline. The other way out is on the distro side. rtl_bt/rtl8761cu_fw.bin has been in linux-firmware since 20251111, so a newer firmware-realtek package fixes this without any kernel change. -- Thanks, Sasha
