Using gcc 4.4.5 on a Powerbook G4 with a PPC cpu, a complicated
if statement results in incorrect flow, whereas the equivalent switch

    mac80211: fix suspend/resume races with unregister hw

Above commit add rtnl_lock() into wiphy_register(), what cause deadlock
when initializing ipw2x00 driver, which itself call wiphy_register()
from register_netdev() internal callback with rtnl mutex taken.

To fix move wiphy_register() outside register_netdev(). This solution
have side effect of not creating /sys/class/net/wlanX/phy80211 link,
but that's a minor issue we can live with.

During the association, the regulatory is updated by country IE
that reaps the previously found beacons. The impact is that
after a STA disconnects *or* when for any reason a regulatory
domain change happens the beacon hint flag is not cleared
therefore preventing future beacon hints to be learned.
This is important as a regulatory domain change or a restore
of regulatory settings would set back the passive scan and no-ibss
flags on the channel. This is the right place to do this given that
it covers any regulatory domain change.

If the command queue is constantly busy,
which can happen in P2P, the hangcheck
timer will frequently find a command in
it and will eventually reset the device
because nothing sets the timestamp for
this queue when commands are processed.

Fix this by setting the timestamp when
a command completes.

unregistering the hardware etc. so we should bail out immediately when
we get drv_flush callback from mac80211 when the card is being unplugged.
the panic occurs after we had associated to an AP.

Since my commit 34e89507
("mac80211: allow station add/remove to sleep") there is
a race in mac80211 when it clears the TIM bit because a
sleeping station disconnected, the spinlock isn't held
around the relevant code any more. Use the right API to
acquire the spinlock correctly.

If is_main_vif(ar, vif) reports that we have to fall back
to software encryption, we goto err_softw; before locking ar->mutex.
As a result, we have unprotected call to carl9170_set_operating_mode
and unmatched mutex_unlock.

The patch fix the issue by adding mutex_lock before goto.

wl1271_sdio_power_on checks if the return value of pm_runtime_get_sync
is non-zero, and if so bails out.
However, pm_runtime_get_sync can return a positive number which does not
suggest an error has occurred. This is problematic for two reasons:

1. The function will needlessly bail out without decrementing back the
   runtime PM reference counter.
2. wl1271_power_on only checks if wl1271_power_on return value is
   negative. This means that wl1271_power_on will continue even if
   wl1271_sdio_power_on bailed out. As a result, sdio transactions will
   be initiated without properly enabling the sdio function and claiming
   the host. This could even lead to a kernel panic.

Fix this by only checking that the return value of pm_runtime_get_sync
is non-negative.

The testmode NVS push command is no longer in use. In addition, it has
several implementation issues that prevent it from working correctly:

1. wl1271_tm_cmd_configure relies on wl->chip.id being set. However,
   since the device was not necessarily booted by the time the function
   is called, wl->chip.id will be initialized to 0.
2. The NVS file is fetched by calling request_firmware() before it is
   possible to push an NVS file.
3. The maximum allowed size of nl binary payloads is not sufficient for
   pushing NVS files.
4. Pushing 128x NVS files will always fail due to a bug in the
   validation code.
5. In case the pushed NVS file is found invalid, the mutex will be kept
   locked and the nvs member will become a dangling pointer.

Since this feature is not being used, remove it completely instead of
fixing it.

Due to some recent optimization done in the way the mac address
bytes are written into the OTP memory, some AR9485 chipsets were
forced to use the first byte from the eeprom template and the
remaining bytes are read from OTP.

AR9485 happens to use generic eeprom template which has 0x1 as
the first byte causes issues in bringing up the card.

So fixed the eeprom template accordingly to address the issue.

When an hidp connection is added for a boot protocol input
device, don't release a device reference that was never
acquired. The device reference is acquired when the session
is linked to the session list (which hasn't happened yet when
hidp_setup_input is called).

When an hidp connection is added for a boot protocol input
device, only free the allocated device if device registration fails.
Subsequent failures should only unregister the device (the input
device api documents that unregister will also free the allocated
device).

Commit fada4ac3 introduced the usage of kthread API.
kthread_stop is a blocking function which returns only when
the thread exits. In this case, the thread can't exit because it's
waiting for the write lock, which is being held by cmtp_del_connection()
which is waiting for the thread to exit -- deadlock.

Revert cmtp_reset_ctr to its original behavior: non-blocking signalling
for the session to terminate.

Commit f4d7cd4a introduced the usage of kthread API.
kthread_stop is a blocking function which returns only when
the thread exits. In this case, the thread can't exit because it's
waiting for the write lock, which is being held by bnep_del_connection()
which is waiting for the thread to exit -- deadlock.

Use atomic_t/wake_up_process instead to signal to the thread to exit.

No command should be send before Command Complete event for HCI
reset is received. This fix regression introduced by commit
6bd32326(Bluetooth: Use proper timer for hci command timout)
for chips whose reset command takes longer to complete (e.g. CSR)
resulting in next command being send before HCI reset completed.
