What _really_ is the return value meaning of omap_hwmod_register() ? If it's zero for success, negative for error codes, then don't be clever and try to use IS_ERR_VALUE() for that - just use a standard < 0 test instead. You only need to use IS_ERR_VALUE() for stuff that may return negative errno values _and_ which may return valid addresses which may be misinterpreted as negative numbers. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
