If the character ":" is present in the value it terminates the path. The value may be an alias. If the stdin-path property is not specified, stdout-path should be assumed to define the input device. So, this function needs to do three more things: - also look for 'stdout-path' (in addition to 'linux,stdout-path') - Parse for a ':' in the path and trim that off so it can be used for arguments. (Bonus: return the arguments to the caller) - make sure that it can handle the path containing an alias (I've just not checked if the current code will handle this) g. -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
