[ALSA] sound: snd_register_device_for_dev fix
snd_register_device_for_dev() can oops when device_create() returns ERR_PTR(err). Scenario: preg->dev = device_create(...); /* fails */ if (preg->dev) /* contains ERR_PTR(err) */ dev_set_drvdata(preg->dev, private_data); and dev_set_drvdata() looks like this: static inline void dev_set_drvdata (struct device *dev, void *data) { dev->driver_data = data; <--- boom } This patch should prevent that.
