[Test Case]

Basic bluetooth, wifi operations. This is verified with all related kernel/series combinations:
* linux-hwe5.19/jammy
* linux-hwe-6.2/jammy
* linux-oem-6.0/jammy
* linux-oem-6.1/jammy
* linux-oem-6.5/jammy
* ilnux/mantic

[Where problems could occur]

New device firmware blob, even blob format changes. Expect bugs, power consumption issues, etc.

[Other Info]

Bluetooth V2 firmware support was first landed to v6.4, and the binary rename in linux-next now. To preserve consistency, Unstable, Mantic and OEM-6.5 kernels are nominated for fix. As for linux-firmware, the only target is Jammy.

[You-Sheng Yang (vicamo)]

Still figuring out potential upstream bluetooth firmware regression in https://lore.kernel.org/linux-firmware/20230703134824.7795b277@smeagol/

[You-Sheng Yang (vicamo)]

So if we have to support the v2 format binary firmware in jammy for linux-oem-6.5/jammy, which will certainly affects hwe kernels in jammy as well, which in turn affects linux-hwe-5.19/jammy derived from linux-generic/kinetic, linux-hwe-6.2/jammy derived from linux-generic/lunar, and linux-hwe-6.4/jammy derived from linux-generic/mantic. Basically everything.

[You-Sheng Yang (vicamo)]

So V2 blob rename patch is out, I believe we will only add a separate V2 blob to Jammy and no interference will be made to Lunar kernel. Mantic kernel/firmware will need to be updated as well.

[You-Sheng Yang (vicamo)]

kernel patch applied: https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/commit/?id=77bceb7a4d68

[You-Sheng Yang (vicamo)]

linux-firmware/mantic now includes changes for RTL8851CE V2, so kernel part should be updated as well:
* 42d31f8f6 rtl_bt: Add firmware v2 file for RTL8852C
* 7ed62638b Revert "rtl_bt: Update RTL8852C BT USB firmware to 0x040D_7225"

[You-Sheng Yang (vicamo)]

Verified:
* linux-hwe5.19/jammy
* linux-hwe-6.2/jammy
* linux-oem-6.0/jammy
* linux-oem-6.1/jammy
* linux-oem-6.5/jammy
* ilnux/mantic

Will then SRU.
