cppcheck warning:
sound/soc/samsung/smdk_wm8994.c:179:6: style: Variable 'ret' is reassigned a value before the old one has been used. [redundantAssignment] ret = devm_snd_soc_register_card(&pdev->dev, card); ^ sound/soc/samsung/smdk_wm8994.c:166:8: note: ret is assigned ret = -EINVAL; ^ sound/soc/samsung/smdk_wm8994.c:179:6: note: ret is overwritten ret = devm_snd_soc_register_card(&pdev->dev, card); ^
The initial authors bothered to set ret to -EINVAL and throw a dev_err() message, so it looks like there is a missing return to avoid continuing if the property is missing.
