Why is this required? There is no bug in the current code, so no need to change it at all. Please just use sysfs_emit() for new sysfs files, no need to churn the tree and change all existing entries, otherwise we would have done this a long time ago when we introduced these functions. thanks, greg k-h _______________________________________________ linux-snps-arc mailing list linux-snps-arc@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-snps-arc
