    libnvdimm, dimm: handle EACCES failures from label reads · e7c5a571
    Dan Williams authored
    The new support for the standard _LSR and _LSW methods neglected to also
    update the nvdimm_init_config_data() and nvdimm_set_config_data() to
    return the translated error code from failed commands. This precision is
    necessary because the locked status that was previously returned on
    ND_CMD_GET_CONFIG_SIZE commands is now returned on
    ND_CMD_{GET,SET}_CONFIG_DATA commands.
    
    If the kernel misses this indication it can inadvertently fall back to
    label-less mode when it should otherwise avoid all access to locked
    regions.
