Kuninori Morimoto 98e5eb1100 ALSA: hda/ca0132: fixup buffer overrun at tuning_ctl_set()
tuning_ctl_set() might have buffer overrun at (X) if it didn't break
from loop by matching (A).

	static int tuning_ctl_set(...)
	{
		for (i = 0; i < TUNING_CTLS_COUNT; i++)
(A)			if (nid == ca0132_tuning_ctls[i].nid)
				break;

		snd_hda_power_up(...);
(X)		dspio_set_param(..., ca0132_tuning_ctls[i].mid, ...);
		snd_hda_power_down(...);                ^

		return 1;
	}

We will get below error by cppcheck

	sound/pci/hda/patch_ca0132.c:4229:2: note: After for loop, i has value 12
	 for (i = 0; i < TUNING_CTLS_COUNT; i++)
	 ^
	sound/pci/hda/patch_ca0132.c:4234:43: note: Array index out of bounds
	 dspio_set_param(codec, ca0132_tuning_ctls[i].mid, 0x20,
	                                           ^
This patch cares non match case.
