Update the cfg layer with active channel list after

Problem description:
 - wl_dealloc_netinfo would free allocated wireless_dev structures, which has
   work_struct for wdev_cleanup_work
 - If there is any job scheduled for wdev_cleanup_work and if it

 - But simply waiting for wdev_cleanup_work completion in

 - Upon a detach, only remove the interface, and schedule a deallocation of it

staging: ozwpan: Cancel hrtimer before expiry set

Currently oz_timer_add sets the new expiry time before calling
hrtimer_start_expires where the timer is actually updated in the
timerqueue.

However, this update to expiry time is racy because the the
hrtimer_set_expires call is being performed from a softirq or a thread's
context. The CPU could recieve a hrtimer_interrupt before the
hrtimer_start_expires call but after hrtimer_set_expires.

This would leave the hrtimer with a new expiry value but with the same
position in the rbtree which a subsequent hrtimer_interrupt could use
to perform its timerqueue add/del operations with. Leaving the rbtree
in this stale/bad state causes some timers to never get serviced.

Fix this by first removing the timer from the timerqueue by calling
hrtimer_cancel and then updating the expiry time.

bdi: avoid oops on device removal

implementation with unbound workqueue") when device is removed while we
are writing to it we crash in bdi_writeback_workfn() ->
set_worker_desc() because bdi->dev is NULL.

This can happen because even though bdi_unregister() cancels all pending
flushing work, nothing really prevents new ones from being queued from
balance_dirty_pages() or other places.

Fix the problem by clearing BDI_registered bit in bdi_unregister() and
checking it before scheduling of any flushing work.

media: tegra: nvavp: fix deadlock issue

nvavp_uninit() cancels clock_disable_work in a synchronous manner,
and the work function of clock_disable_work requires nvavp->open_lock,
so any routine holds the same lock should release it before calling
nvavp_uninit().

bcmdhd: Override fw's check for flowcontrol

The broadcom firmware sends a flowcontrol status in the rx packet
indicating that it is running short on tx buffers. This bit is used to
tell the driver to stop sending packets (based on their priority).

However, there seems to be a significantly large delay (~100ms) in the
fw updating the driver with the new flowcontrol bits.

Ozmo's audio traffic is marked as 0x106 priority which translates to
priority=0x40.

This change overrides the flowcontrol bits sent by the fw
and makes it so that the 0x40 priority traffic is never blocked from
flowcontrol. The DATAOK(bus) check on the bus ensures that we always
have enough tx buffers on the chip (despite the flowcontrol being set)
and that we don't end up clobbering packets on the fw.
