You can not have multiple values in a single sysfs file. sysfs is "one value per file". This needs to be individual files, if you really need this. And never a "header" for a sysfs file, that's never something that should ever be in a sysfs file. And finally, you need a Documentation/ABI/ update for any sysfs file changes. thanks, greg k-h _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
