There are two different variants for Hauppauge WinTV MiniCard:

	[SMS1XXX_BOARD_HAUPPAUGE_TIGER_MINICARD] = {
		.name	= "Hauppauge WinTV MiniCard",
		.type	= SMS_NOVA_B0,
		.fw[DEVICE_MODE_DVBT_BDA] = SMS_FW_DVBT_HCW_55XXX,
		.default_mode = DEVICE_MODE_DVBT_BDA,
		.lna_ctrl  = 29,
		.board_cfg.foreign_lna0_ctrl = 29,
		.rf_switch = 17,
		.board_cfg.rf_switch_uhf = 17,
	},
	[SMS1XXX_BOARD_HAUPPAUGE_TIGER_MINICARD_R2] = {
		.name	= "Hauppauge WinTV MiniCard Rev 2",
		.type	= SMS_NOVA_B0,
		.fw[DEVICE_MODE_DVBT_BDA] = SMS_FW_DVBT_HCW_55XXX,
		.default_mode = DEVICE_MODE_DVBT_BDA,
		.lna_ctrl  = -1,
	},

As it can be seen, the RF part of the definitions are different.

So, better to use different names in order to distinguish
between them.
