Define structures for the copy engine ctrl/misc registers,
that includes CE CMD halt, watermark source, watermark destination,
host IE ring, source, destination and dmax ring.
This adds support to avoid the conditional compilation,
code optimization and dynamic configuration of the copy engine

USB devices rely on queuing functionality provided by the fwsignal
module regardless the mode fwsignal is operating in. For this some
data structure needs to be reserved which is tied to the interface,
which is done by brcmf_fws_add_interface(). However, it checks the
mode. Replace that by checking result from brcmf_fws_queue_skbs().
Otherwise the driver will crash in a null pointer dereference when
data is transmitted on the interface.

When request firmware fails, brcmf_ops_sdio_remove is being called and
brcmf_bus freed. In such circumstancies if you do a suspend/resume cycle
the kernel hangs on resume due a NULL pointer dereference in resume
function. So in brcmf_sdio_firmware_callback() we need to unbind the
driver from both sdio_func devices when firmware load failure is indicated.

When firmware loading failed the code used to unbind the device provided
by the calling code. However, for the sdio driver two devices are bound
and both need to be released upon failure. The callback has been extended
with parameter to pass error code so add that in this commit upon firmware
loading failure.

Extend the parameters in the firmware callback so it can be called
upon success and failure. This allows the caller to properly clear
all resources in the failure path. Right now the error code is

An earlier change to this function (3bdae810721b) fixed a leak in the
case of an unsuccessful call to brcmf_sdiod_buffrw(). However, the
glom_skb buffer, used for emulating a scattering read, is never used
or referenced after its contents are copied into the destination
buffers, and therefore always needs to be freed by the end of the
function.

This change adds support for multi-scheduled scan in the driver. It
currently relies on g-scan support in firmware and will set struct
wiphy::max_sched_scan_reqs accordingly. This is limited to 16 concurrent
requests.
The firmware currently has a limit of 64 channels that can be configured
for all requests in total regardless whether there are duplicates. So if
a request uses 35 channels there are 29 channels left for another request.
When user-space does not specify any channels cfg80211 will add all
channels defined by the wiphy instance to the request, which makes
reaching the limit rather easy for dual-band devices.

git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-next
First batch of iwlwifi driver patches 4.13
* Loads of FW API documentation improvements (for tools and htmldoc);
* Continued work for the new A000 family;
* Bumped the maximum supported FW API to 31;
* Improve the differentiation between 8000, 9000 and A000 families;
* A lot of fixes and cleanups here and there;
kvalo: There were conflicts iwl_mvm_stop_device() and
iwl_mvm_tcool_set_cur_state(). The former was easy but latter needed more
thought. Apparently the mutex was taken too late, so I fixed so that the mutex
is taken first and then check for iwl_mvm_firmware_running().

Network devices can allocate reasources and private memory using
netdev_ops->ndo_init(). However, the release of these resources
can occur in one of two different places.
Either netdev_ops->ndo_uninit() or netdev->destructor().
The decision of which operation frees the resources depends upon
whether it is necessary for all netdev refs to be released before it
is safe to perform the freeing.
netdev_ops->ndo_uninit() presumably can occur right after the
NETDEV_UNREGISTER notifier completes and the unicast and multicast
address lists are flushed.
netdev->destructor(), on the other hand, does not run until the
netdev references all go away.
Further complicating the situation is that netdev->destructor()
almost universally does also a free_netdev().
This creates a problem for the logic in register_netdevice().
Because all callers of register_netdevice() manage the freeing
of the netdev, and invoke free_netdev(dev) if register_netdevice()
fails.
If netdev_ops->ndo_init() succeeds, but something else fails inside
of register_netdevice(), it does call ndo_ops->ndo_uninit(). But
it is not able to invoke netdev->destructor().
This is because netdev->destructor() will do a free_netdev() and
then the caller of register_netdevice() will do the same.
However, this means that the resources that would normally be released
by netdev->destructor() will not be.
Over the years drivers have added local hacks to deal with this, by
invoking their destructor parts by hand when register_netdevice()
fails.
Many drivers do not try to deal with this, and instead we have leaks.
Let's close this hole by formalizing the distinction between what
private things need to be freed up by netdev->destructor() and whether
the driver needs unregister_netdevice() to perform the free_netdev().
netdev->priv_destructor() performs all actions to free up the private
resources that used to be freed by netdev->destructor(), except for
free_netdev().
netdev->needs_free_netdev is a boolean that indicates whether
free_netdev() should be done at the end of unregister_netdevice().
Now, register_netdevice() can sanely release all resources after
ndo_ops->ndo_init() succeeds, by invoking both ndo_ops->ndo_uninit()
and netdev->priv_destructor().
And at the end of unregister_netdevice(), we invoke
netdev->priv_destructor() and optionally call free_netdev().

In case an assert happens on init flow, the current
driver powers down the NIC, except if iwlmvm modparam

Extend this capability to cover most failure cases
by keeping track of what init configurations have been
completed. This way, we can allow NOT powering down
the NIC, while making sure that when the driver is
removed we don't try to free resources that haven't
been allocated. (This can result in a kernel panic.)
