Re: [alsa-devel] ASoC: add Renesas R-Car module feature

Hello Kuninori Morimoto,

This is a semi-automatic email about new static checker warnings.

The patch cdaa3cdfb4a7: "ASoC: add Renesas R-Car module feature" from Jul 21, 2013, leads to the following Smatch complaint:

sound/soc/sh/rcar/core.c:294 rsnd_dai_connect() warn: variable dereferenced before check 'mod' (see line 291)

sound/soc/sh/rcar/core.c 290 { 291 struct rsnd_priv *priv = rsnd_mod_to_priv(mod); ^^^^^^^^^^^^^^^^^^^^^ Dereference.

292 struct device *dev = rsnd_priv_to_dev(priv); 293 294 if (!mod) { ^^^^ Check.

295 dev_err(dev, "NULL mod\n"); 296 return -EIO;

regards, dan carpenter
