848879340a uwb: create a uwb bus type and add in-range peer devices to it
Documentation/usb/WUSB-Design-overview.txt states that UWB devices seen
by a UWB radio controller are added to /sys/bus/uwb/devices, but this
was not actually being done.  This functionality is needed in order for
UWB peer devices to be enumerated by user mode tools.  This patch
creates a uwb bus type and adds UWB peer devices to it as they are
discovered by the radio controller.

675f0ab2fe uwb: init beacon cache entry before registering uwb device
Make sure the uwb_dev->bce entry is set before calling uwb_dev_add in
uwbd_dev_onair so that usermode will only see the device after it is
properly initialized.  This fixes a kernel panic that can occur if
usermode tries to access the IEs sysfs attribute of a UWB device before
the driver has had a chance to set the beacon cache entry.

90ec00d54e uwb: fix channel change failure
Make the transition to the UWB_RSV_STATE_NONE state synchronous so that
there is not a race between uwb_rsv_terminate and uwb_rsv_establish.
uwb_rsv_terminate would set the rsv->state to UWB_RSV_STATE_NONE but did
not release the stream resource until a 320ms timeout had expired.  If a
user called uwb_rsv_establish during that time, it could fail to
establish the reservation because no stream resources were available.
This patch removes the timer from the uwb_rsv_terminate process since it
is not needed when transitioning to UWB_RSV_STATE_NONE.

1fc671b3be uwb: move mutex_lock to error case in uwbd_evt_handle_rc_bp_slot_change
Only acquire rc->uwb_dev.mutex in the error case in
uwbd_evt_handle_rc_bp_slot_change.  This fixes a bug where establishing
a reservation on a new channel will fail if we were unable to establish
a reservation on the previous channel due to DRP conflict.

If rc->uwb_dev.mutex is acquired in the non-error case when the uwb
system is attempting to start beaconing, it will block because the start
beaconing code is holding this mutex.  This prevents any other
notifications from the URC from being processed.  In particular, the
DRP_AVAILABILITY notification will not be processed during the start
beaconing process which can result in a failure to establish a
reservation.  It is safe to not hold the mutex in the non-error
case since the only other place rc->uwb_dev.beacon_slot is accessed is
in the same worker thread that uwbd_evt_handle_rc_bp_slot_change
executes in.

fbbde074ab UWB: fix sysfs warning on HWA device unplug.
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.

c654ecbbfe HWA RC: fix a kernel panic when unplugging the HWA dongle
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.

a899575191 USB: HWA: fix device probe failure
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.

a451eaf9c5 uwb: Use kcalloc instead of kzalloc to allocate array
The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.

in https://lkml.org/lkml/2011/11/25/107

fe7484834b USB: convert some miscellanies drivers to use module_usb_driver()
This converts the remaining USB drivers in the kernel to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

475c0a6b2c uwb: Add export.h for EXPORT_SYMBOL/THIS_MODULE as required
These macros are no longer in module.h and module.h is no longer
present everywhere.  Call out export.h for the real users who
are making use of these macros, or else we'll get things like:

 CC      drivers/uwb/umc-drv.o
drivers/uwb/umc-dev.c:42: warning: data definition has no type or storage class
drivers/uwb/umc-dev.c:42: warning: type defaults to ‘int’ in declaration of ‘EXPORT_SYMBOL_GPL’
drivers/uwb/umc-dev.c:42: warning: parameter names (without types) in function declaration

c7394efc26 uwb: Add module.h to the real uwb modular users.
Lots of files were getting an implicit include of module.h
for years now.  But that will be fixed shortly.  So get the
real users to call out the include explicitly.

0b992080a9 drivers/uwb: fix implicit use of stat.h
The module.h (via device.h) was pulling handfuls of implicitly present
header files -- including basic stuff like stat.h.  Fix up these stat.h
users in advance so they don't break on the cleanup.

129220848c Remove unneeded version.h include from drivers/uwb/

linux/version.h is not needed in drivers/uwb/uwb-internal.h .
This patch removes it.
