[PATCH] fix 5.15 init regression for Intel Bluetooth

[Ortwin Glück]

Hi

On all 5.15 kernels the Intel Bluetooth no longer works. All was fine in 5.14.
Apparently the quirk is needed for this device.

vanilla 5.15.5:
   Bluetooth: hci0: Reading Intel version command failed (-110)
   Bluetooth: hci0: command tx timeout

with patch:
   Bluetooth: hci0: Legacy ROM 2.5 revision 1.0 build 3 week 17 2014
   Bluetooth: hci0: Intel device is already patched. patch num: 32

Please apply to stable too.

Thanks
