This is weird.

>From drivers/media/platform/uniphier/Makefile,
obviously you link all the objects into the single module, uniphier-dvb.ko


It contains zero, one, or two sets of MODULE_* depending on CONFIG options.


 - Zero MODULE_LICENSE / MODULE_AUTHOR / MODULE_DESCRIPTION
   if CONFIG_DVB_UNIPHIER_LD11_ISDB=n &&
      CONFIG_DVB_UNIPHIER_LD20_ISDB=n


 - Two sets of MODULE_LICENSE / MODULE_AUTHOR / MODULE_DESCRIPTION
   if CONFIG_DVB_UNIPHIER_LD11_ISDB=y &&
      CONFIG_DVB_UNIPHIER_LD20_ISDB=y



What you can do is:

 - Split the module into core, ld11, ld20

    or

 - Move the module tags and entry to hsc-core.c
   and leave only the data arrays in ld11, ld20.
