Hello,

I see this error in /sound/soc/codecs/tlv320aic23.c:

static inline unsigned int tlv320aic23_read_reg_cache(struct snd_soc_codec ^^^^^^^^ *codec, unsigned int reg) { u16 *cache = codec->reg_cache; if (reg >= ARRAY_SIZE(tlv320aic23_reg)) return -1; ^^ return cache[reg]; }

Maybe better return 0? Best read the codec datasheet to find a safe or non-existing value? And also a "printk(KERN_ERR " then? Actually, better just remove the check, because if you want to write a codec register, you must know what you are doing?

I am busy with the codec driver for mc13783. Currently, the mc13783 (from Sascha Hauer) code does not check 'reg'.

(I want to supply a patch finally, but as newbie: from which GIT?, because mine is a merge of 2 branches of the Pengutronix GIT)

Regards, Jürgen
