From 0c4db6df915bc470f0cd32fe48287fa6eb6adfb4 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Fri, 8 Jan 2010 12:56:42 -0500 Subject: USB: use the device lock for persist_enabled This patch (as1325) changes the locking for the persist_enabled flag in struct usb_device. Now it is protected by the device lock, along with all its neighboring bit flags, instead of the PM lock (which is about to vanish anyway).
