Aditya Shankar 1d4f1d53e1 Staging: wilc1000: Fix kernel Oops on opening the device
Commit 2518ac59eb ("staging: wilc1000: Replace kthread with workqueue
for host interface") adds an unconditional destroy_workqueue() on the
wilc's "hif_workqueue" soon after its creation thereby rendering
it unusable. It then further attempts to queue work onto this
non-existing hif_worqueue and results in:

This fix removes the unnecessary call to destroy_workqueue() while opening
the device to avoid the above kernel panic. The deinit routine already
does a good job of terminating the workqueue when no longer needed.

Avraham Stern 1d76250bd3 nl80211: support beacon report scanning
Beacon report radio measurement requires reporting observed BSSs
on the channels specified in the beacon request. If the measurement
mode is set to passive or active, it requires actually performing a
scan (passive or active, accordingly), and reporting the time that
the scan was started and the time each beacon/probe was received
(both in terms of TSF of the BSS of the requesting AP). If the
request mode is table, this information is optional.
In addition, the radio measurement request specifies the channel
dwell time for the measurement.

In order to use scan for beacon report when the mode is active or
passive, add a parameter to scan request that specifies the
channel dwell time, and add scan start time and beacon received time
to scan results information.

Supporting beacon report is required for Multi Band Operation (MBO).

which have the following element:

happen. Removing the checks since they will always be true.

Linus Torvalds 2f37dd131c Staging and IIO driver update for 4.7-rc1
Here's the big staging and iio driver update for 4.7-rc1.
 
 I think we almost broke even with this release, only adding a few more
 lines than we removed, which isn't bad overall given that there's a
 bunch of new iio drivers added.  The Lustre developers seem to have
 woken up from their sleep and have been doing a great job in cleaning up
 the code and pruning unused or old cruft, the filesystem is almost
 readable :)
 
 Other than that, just a lot of basic coding style cleanups in the churn.
 All have been in linux-next for a while with no reported issues.

Kangjie Lu d13829686b staging: wilc1000: fix infoleak in wilc_wfi_cfgoperations
"mac" is an array allocated in stack without being initialized,
and will be sent out via "nla_put". The dump_station() is supposed
to initialize the mac address; otherwise, sensitive data in kernel
stack will be leaked. To fix this, copy the mac address to it.
