Pull driver core / sysfs patches from Greg KH:
 "Here's the big driver core / sysfs update for 3.13-rc1.

  There's lots of dev_groups updates for different subsystems, as they
  all get slowly migrated over to the safe versions of the attribute
  groups (removing userspace races with the creation of the sysfs
  files.) Also in here are some kobject updates, devres expansions, and
  the first round of Tejun's sysfs reworking to enable it to be used by
  other subsystems as a backend for an in-kernel filesystem.

  All of these have been in linux-next for a while with no reported
  issues"

UWB: clean up attribute use by using ATTRIBUTE_GROUPS()

2013-10-29T23:43:36+00:00

The ATTRIBUTE_GROUPS() macro can be used in the uwb code to reduce the
number of lines of code.

uwb: convert bus code to use dev_groups

2013-10-17T01:36:02+00:00

The dev_attrs field of struct bus_type is going away soon, dev_groups
should be used instead.  This converts the uwb bus code to use the
correct field.

uwb: Staticize local symbols

2013-08-20T00:08:16+00:00

These local symbols are used only in this file.
Fix the following sparse warnings:

drivers/uwb/drp-ie.c:30:5: warning: symbol 'uwb_rsv_reason_code' was not declared. Should it be static?
drivers/uwb/drp-ie.c:58:5: warning: symbol 'uwb_rsv_companion_reason_code' was not declared. Should it be static?

UWB: fix sysfs warning on HWA device unplug.

2013-08-12T22:41:09+00:00

In the disconnect routine for the hwa_hc interface, it calls
uwb_pal_unregister to unregister itself from the UWB subsystem.  This
function attempts to clean up the link to the host controller directory in
the device's UWB radio control interface directory.  If the disconnect
routine for the radio control interface has already run, the uwb directory
will be gone so the call to sysfs_remove_link generates a warning.

HWA RC: fix a kernel panic when unplugging the HWA dongle

2013-08-12T22:41:08+00:00

This patch fixes a kernel panic that can occur when unplugging the HWA
dongle while a downstream device is in the process of disconnecting.
This involved 2 changes.  First, call usb_lock_device_for_reset before
usb_reset_device to synchronize the HWA's post_rest and disconnect
routines.  Second, set the hwarc->neep_urb and hwarc->rd_buffer to NULL
when they are freed in the error path in the post_reset routine.  This
prevents a double free when the disconnect routine is called and attempts
to free those resources again.

drivers: avoid format string in dev_set_name

2013-07-03T23:07:41+00:00

Calling dev_set_name with a single paramter causes it to be handled as a
format string.  Many callers are passing potentially dynamic string
content, so use "%s" in those cases to avoid any potential accidents,
including wrappers like device_create*() and bdi_register().

USB: HWA: fix device probe failure

2013-06-24T23:20:43+00:00

This patch fixes a race condition that caused the HWA_HC interface probe
function to occasionally fail.  The HWA_HC would attempt to register
itself with the HWA_RC by searching for a uwb_rc class device with the
same parent device ptr.  If the probe function for the HWA_RC interface
had yet to run, the uwb_rc class device would not have been created
causing the look up to fail and the HWA_HC probe function to return an
error causing the device to be unusable.

The fix is for the HWA to delay registering with the HWA_RC until
receiving the command from userspace to start the wireless channel.  It
is the responsibility of userspace to ensure that the uwb_rc class
device has been created before starting the HWA channel.
