    V4L/DVB (4751): Fix DBV_FE_CUSTOMISE for card drivers compiled into kernel · c5dec9fb
    Trent Piepho authored
    When a front-end is disabled, card drivers that use it are compiled with
    a stub version of the front-end's attach function.  This way they have no
    references to the front-end's code and don't need it to be loaded.
    If a card driver is compiled into the kernel, and a front-end is a
    module, then that front-end is effectively disabled wrt the card driver. 
    In this case, the card driver should get the stub version.  This was not
    happening.
    The stub vs real attach function selection is changed so that when the
    front-end is a module the real attach function is only used if the card
    driver is a module as well.  This means a module front-end will be
    supported by card drivers that are modules and not supported by card
    drivers compiled into the kernel.
