From da259465d7526804b21d274281fb4d60b4216c82 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 2 Apr 2013 01:25:09 +0200 Subject: USB / PM: Don't try to hide PM QoS flags from usb_port_device_release() Remove the call to dev_pm_qos_hide_flags(), added by commit 6e30d7cb "usb: Add driver/usb/core/(port.c,hub.h) files", from usb_port_device_release(), because (1) it is completely unnecessary (the flags have been removed already by the PM core during the unregistration of the device object) and (2) it triggers a NULL pointer dereference in sysfs_find_dirent() (dev->kobj.sd is NULL at this point).
