This is often because devlink_fmsg_obj_nest_start lacks a __init annotation or the annotation of .L0 is wrong. -- The function devlink_fmsg_obj_nest_end() references the variable __init .L0 . This is often because devlink_fmsg_obj_nest_end lacks a __init annotation or the annotation of .L0 is wrong. -- The function hci_free_adv_monitor() references the variable __init .L0 . This is often because hci_free_adv_monitor lacks a __init annotation or the annotation of .L0 is wrong. -- The function hci_add_adv_monitor() references the variable __init .L0 . This is often because hci_add_adv_monitor lacks a __init annotation or the annotation of .L0 is wrong. -- FATAL: modpost: The relocation at __ex_table+0x1710 references section ".debug_str" which is not executable, IOW it is not possible for the kernel to fault at that address.
