    OK, I just looked over it. What about dib0700_rc_query_old_firmware,
    that would also need to be fixed.

    I don't have an overview over the media framework, so I wonder what
    arbitrates concurrent access to the buffer? Functions which are only
    called from the initialization and probe routines are probably properly
    arbitrated by the driver core. But I would expect (perhaps
    that is me being naive) stuff like dib0700_change_protocol to need some
    sort of mutex ?

    It seems to be called from some /sys/class/*/ file while for example
    legacy_dvb_usb_read_remote_control, which calls dib0700_rc_query_old_firmware, is
    described as being a polling function, i.e. periodically executed...
    or the streaming_ctrl function, that looks like it is executed at


    can you add yourself to the
    MAINTAINERS file please?
