From cc583db3d708886ef89bce9d686419c58400182c Mon Sep 17 00:00:00 2001 From: Paul Bolle Date: Wed, 2 Jul 2014 12:10:45 +0200 Subject: [PATCH] Documentation: sysfs-bus-usb: update power/persist description There's no power/persist file for hubs. And CONFIG_USB_PERSIST was removed in v2.6.26. Update the description of power/persist accordingly. Also remove the line on its default value. It is not entirely correct, as CONFIG_USB_DEFAULT_PERSIST and the USB_QUIRK_RESET flag influence the default. It is not needed to understand this file anyhow.
