* uwb: Remove umc bus legacy suspend/resume supportLars-Peter Clausen2015-03-181-34/+0
| | | | | | | | | | There are currently no umc drivers implementing suspend/resume, so remove the legacy suspend/resume support from the framework. If a umc driver ever wants to implement suspend/resume they can use dev_pm_ops, which works out of the box without any additional support necessary from the bus itself.

* uwb/whci: Delete an unnecessary check before the function call ↵Markus Elfring2015-03-181-2/+1
| | | | | | | | | | | | "umc_device_unregister" The umc_device_unregister() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed.

| | | | | | | | | | | | 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.

* uwb: fix channel change failureThomas Pugliese2014-05-271-1/+6
| | | | | | | | | | | | | | 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.

* uwb: move mutex_lock to error case in uwbd_evt_handle_rc_bp_slot_changeThomas Pugliese2013-12-201-2/+2
| | | | | | | | | | | | | | | | | | | | | 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.

* UWB: fix sysfs warning on HWA device unplug.Thomas Pugliese2013-08-131-2/+38
| | | | | | | | | | | | 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 dongleThomas Pugliese2013-08-131-1/+15
| | | | | | | | | | | | | | 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.

* USB: HWA: fix device probe failureThomas Pugliese2013-06-252-1/+4
| | | | | | | | | | | | | | | | | | 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.

| * uwb: Use kcalloc instead of kzalloc to allocate arrayThomas Meyer2011-12-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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. The semantic patch that makes this change is available in https://lkml.org/lkml/2011/11/25/107 Signed-off-by: Thomas Meyer <thomas@m3y3r.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
