In Linux system if you want to use more than 64x please change like this.

  1. media/include/media/dvbdev.h
#if defined(CONFIG_DVB_MAX_ADAPTERS) && CONFIG_DVB_MAX_ADAPTERS > 0
  #define DVB_MAX_ADAPTERS CONFIG_DVB_MAX_ADAPTERS
#else
  #define DVB_MAX_ADAPTERS 64
#endif

change to

//#if defined(CONFIG_DVB_MAX_ADAPTERS) && CONFIG_DVB_MAX_ADAPTERS > 0
//  #define DVB_MAX_ADAPTERS CONFIG_DVB_MAX_ADAPTERS
//#else
//  #define DVB_MAX_ADAPTERS 64
//#endif

#define DVB_MAX_ADAPTERS 128
  1. media/drivers/media/dvb-core/dvbdev.c
#ifdef CONFIG_DVB_DYNAMIC_MINORS
#define MAX_DVB_MINORS          256
#define DVB_MAX_IDS             MAX_DVB_MINORS

change to

#ifdef CONFIG_DVB_DYNAMIC_MINORS
#define MAX_DVB_MINORS          512
#define DVB_MAX_IDS             MAX_DVB_MINORS
