Sorry for late reply! I was busy on another topic...

I've applied your patch, but p2p interface is still not working. I
attached the debug log from wpa_supplicant.

I tested with Linux Kernel 4.0.7 and wpa_supplicant 2.4.

This is my p2p_supplicant.conf:
    ctrl_interface=/var/run/p2p_supplicant
    update_config=1

    device_name=HBM10
    device_type=1-0050F204-1

    p2p_go_ht40=1

Test with the p2p_find command:
    # wpa_cli -p /var/run/p2p_supplicant p2p_find
    Selected interface 'p2p0'
    1928.165036: p2p0: Control interface command 'P2P_FIND'
    FAIL

Best regards
Jörg Krause
