[Impact]
The btrtl driver in the 5.15 jammy kernel sometimes doesn't (re-) load firmware which results in the BT adapter running potentially old firmware rather than the current version from /lib/firmware provided by the linux-firmware package.
[Test Case]
TBD.
[Where Problems Could Occur]
Limited to Realtek USB bluetooth adapters that use the btrl driver. Issues could show up as Bluetooth connection/initialization problems. |

[Impact]
The btrtl driver in the 5.15 jammy kernel sometimes doesn't (re-) load firmware which results in the BT adapter running potentially old firmware rather than the current version from /lib/firmware provided by the linux-firmware package.
This will show in logs like so:
Jul 04 14:57:23 vivo kernel: Bluetooth: hci0: RTL: examining hci_ver=0a hci_rev=dfc6 lmp_ver=0a lmp_subver=d922
Jul 04 14:57:23 vivo kernel: Bluetooth: hci0: RTL: unknown IC info, lmp subver d922, hci rev dfc6, hci ver 000a
Jul 04 14:57:23 vivo kernel: Bluetooth: hci0: RTL: assuming no firmware upload needed
The driver reads subver from the adapter to determine chip type. But that value is overwritten by a firmware load. In the above case, a firmware was already loaded which returns subver d922 which the driver does not recognize and it therefore won't load new firmware.
[Test Case]
TBD. Not sure yet how to reliably reproduce this problem.

[Test Case]
1) Boot machine with USB adapter plugged in.
2) Verify firmware is loaded.
3) Reboot a couple of times and verify that firmware is reloaded every time.
