[alsa-devel] vaio_mux's num_items is not equal to the actual items

[zhejiang]

In patch_sigmatel.c,

static struct hda_input_mux vaio_mux = {
	.num_items = 2,
	.items = {
		/* { "HP", 0x0 }, */
		{ "Mic Jack", 0x1 },
		{ "Internal Mic", 0x2 },
		{ "PCM", 0x3 },
	}
};

Why is the num_items  not 3 ?
The "PCM" won't be selected with num_times = 2.
