Hello Anish Kumar,
The patch 1ff2765182d1: "ASoC: Add max98925 codec driver" from Mar 9, 2015, leads to the following static checker warning:
sound/soc/codecs/max98925.c:274 max98925_rate_value() error: buffer overflow 'rate_table' 9 <= 9
sound/soc/codecs/max98925.c 259 static inline int max98925_rate_value(struct snd_soc_codec *codec, 260 int rate, int clock, int *value, int *n, int *m) 261 { 262 int ret = -EINVAL; 263 int i; 264 265 for (i = 0; i < ARRAY_SIZE(rate_table); i++) { 266 if (rate_table[i].rate >= rate) { 267 *value = rate_table[i].sr; 268 *n = rate_table[i].divisors[clock][0]; 269 *m = rate_table[i].divisors[clock][1]; 270 ret = 0; 271 break; 272 } 273 } 274 dev_dbg(codec->dev, "%s: sample rate is %d, returning %d\n", 275 __func__, rate_table[i].rate, *value); ^^^^^^^^^^^^^^^^^^ If we don't break then we're off by one.
I'm going to just delete this because these warnings are annoying and debug printks are pointless and if you cared then you would have fixed it by now.
