ALSA: hda/ca0132: fixup buffer overrun at tuning_ctl_set()

In the Linux kernel, the following vulnerability has been resolved:

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.
