Please apply the upstream commit:
commit cd9151b618da ("Bluetooth: Fix incorrect pointer arithmatic in ext_adv_report_evt")
Solved kernel BT Err "Bluetooth: Unknown advertising packet type: 0x100"
-------------------------------------------------------------------------
In ext_adv_report_event rssi comes before data (not after data as
in legacy adv_report_evt) so "+ 1" is not required in the ptr arithmatic
to point to next report.
