ASoC: Intel: Fix a buffer overflow issue
0day robot reported a buffer overflow issue:
...
sound/soc/intel/haswell/sst-haswell-pcm.c:1107 hsw_pcm_probe() error: buffer\
overflow 'hsw_dais' 4 <= 4
sound/soc/intel/haswell/sst-haswell-pcm.c:1109 hsw_pcm_probe() error: buffer\
overflow 'hsw_dais' 4 <= 4
...
Fix it by initializing the index(i) to correct value.
