From feccc30d90155bcbc937f87643182a43d25873eb Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Mon, 3 Mar 2008 15:15:59 -0500 Subject: USB: remove CONFIG_USB_PERSIST setting This patch (as1047) removes the USB_PERSIST Kconfig option, enabling it permanently. It also prevents the power/persist attribute from being created for hub devices; there's no point in having it since USB-PERSIST is always turned on for hubs.
