2b6c0e1528 bcma: Use the proper gpio include
The <linux/bcma/bcma_driver_chipcommon.h> is including the legacy
header <linux/gpio.h> to obtain struct gpio_chip. Instead, include
<linux/gpio/driver.h> where this struct is defined.

It turns out that the brcm80211 brcmsmac depends on this to
bring in the symbol gpio_is_valid().

The driver looks up the BCMA parent GPIO driver and checks that
this succeeds, but then it goes on to use the deprecated GPIO
call gpio_is_valid() to check the consistency of the .base
member of the BCMA GPIO struct. The whole check can be dropped
because the bcma_gpio is initialized in the declarations:

  struct gpio_chip *bcma_gpio = &cc_drv->gpio;

And this can never be NULL.

a790cc3a4f wifi: mac80211: add wake_tx_queue callback to drivers
mac80211 is fully switching over to the internal TX queue (iTXQ)
implementation. Update all drivers not yet providing the now mandatory
wake_tx_queue() callback.

As an side effect the netdev interfaces of all updated drivers will
switch to the noqueue qdisc.

965a9d75e3 Merge tag 'trace-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing updates from Steven Rostedt:

 - Runtime verification infrastructure

   This is the biggest change here. It introduces the runtime
   verification that is necessary for running Linux on safety critical
   systems.

   It allows for deterministic automata models to be inserted into the
   kernel that will attach to tracepoints, where the information on
   these tracepoints will move the model from state to state.

   If a state is encountered that does not belong to the model, it will
   then activate a given reactor, that could just inform the user or
   even panic the kernel (for which safety critical systems will detect
   and can recover from).

 - Two monitor models are also added: Wakeup In Preemptive (WIP - not to
   be confused with "work in progress"), and Wakeup While Not Running
   (WWNR).

 - Added __vstring() helper to the TRACE_EVENT() macro to replace
   several vsnprintf() usages that were all doing it wrong.

 - eprobes now can have their event autogenerated when the event name is
   left off.

 - The rest is various cleanups and fixes.

Instead of open coding a __dynamic_array() with a fixed length (which
defeats the purpose of the dynamic array in the first place). Use the new
__vstring() helper that will use a va_list and only write enough of the

046d2e7c50 mac80211: prepare sta handling for MLO support
Currently in mac80211 each STA object is represented
using sta_info datastructure with the associated
STA specific information and drivers access ieee80211_sta
part of it.

With MLO (Multi Link Operation) support being added
in 802.11be standard, though the association is logically
with a single Multi Link capable STA, at the physical level
communication can happen via different advertised
links (uniquely identified by Channel, operating class,
BSSID) and hence the need to handle multiple link
STA parameters within a composite sta_info object
called the MLD STA. The different link STA part of
MLD STA are identified using the link address which can
be same or different as the MLD STA address and unique
link id based on the link vif.

To support extension of such a model, the sta_info
datastructure is modified to hold multiple link STA
objects with link specific params currently within
sta_info moved to this new structure. Similarly this is
done for ieee80211_sta as well which will be accessed
within mac80211 as well as by drivers, hence trivial
driver changes are expected to support this.

For current non MLO supported drivers, only one link STA
is present and link information is accessed via 'deflink'
member.

For MLO drivers, we still need to define the APIs etc. to
get the correct link ID and access the correct part of
the station info.

Currently in mac80211, all link STA info are accessed directly
via deflink. These will be updated to access via link pointers
indexed by link id with MLO support patches, with link id
being 0 for non MLO supported cases.

Except for couple of macro related changes, below spatch takes
care of updating mac80211 and driver code to access to the
link STA info via deflink.

  @ieee80211_sta@
  struct ieee80211_sta *s;

c68115fc53 brcmsmac: rework LED dependencies
This is now the only driver that selects the LEDS_CLASS framework,
which is normally user-selectable. While it doesn't strictly cause
a bug, rework the Kconfig logic to be more consistent with what
other drivers do, and only enable LED support in brcmsmac if the
dependencies are all there, rather than using 'select' to enable
what it needs.

34fe7038a3 brcmsmac: Drop unnecessary NULL check after container_of
The parameter passed to ai_detach() is guaranteed to never be NULL
because it is checked by the caller. Consequently, the result of
container_of() on it is also never NULL, and a NULL check on it
is unnecessary. Even without that, the NULL check would still be
unnecessary because the subsequent kfree() can handle NULL arguments.
On top of all that, it is misleading to check the result of container_of()
against NULL because the position of the contained element could change,
which would make the check invalid. Remove it.

This change was made automatically with the following Coccinelle script.

arrays are 6 bytes addresses.

Although not being a real bug, it is not immediately clear
why is done this way: next 6 bytes address, contiguous to
the first one, must also be copied to next contiguous 6 bytes
address of the destination.

Copying each one separately will make both static analyzers

Check if the block is within BA window and only then check block's
status. Otherwise as Behan wrote: "When I came back to Dublin I
was courtmartialed in my absence and sentenced to death in my absence,
so I said they could shoot me in my absence."

f4443293d7 brcmsmac: fix memory leak in wlc_phy_attach_lcnphy
When wlc_phy_txpwr_srom_read_lcnphy fails in wlc_phy_attach_lcnphy,
the allocated pi->u.pi_lcnphy is leaked, since struct brcms_phy will be
freed in the caller function.

Fix this by calling wlc_phy_detach_lcnphy in the error handler of
wlc_phy_txpwr_srom_read_lcnphy before returning.

b424808115 brcm80211: brcmsmac: Move LEDs to GPIO descriptors
The code in the BRCM80211 BRCMSMAC driver is using the legacy
GPIO API to to a complex check of the validity of the base of
the GPIO chip and whether it is present at all and then adding
an offset to the base of the chip.

Use the existing function to obtain a GPIO line internally
from a GPIO chip so we can use the offset directly and
modernize the code to use GPIO descriptors instead of integers
from the global GPIO numberspace.

====================
wireless-drivers-next patches for 5.5

First set of patches for 5.5. The most active driver here clearly is
rtw88, lots of patches for it. More quiet on other drivers, smaller
fixes and cleanups all over.

This pull request also has a trivial conflict, the report and example
resolution here:

https://lkml.kernel.org/r/20191031111242.50ab1eca@canb.auug.org.au

Major changes:

rtw88

* add deep power save support

* add mac80211 software tx queue (wake_tx_queue) support

* enable hardware rate control

* add TX-AMSDU support

* add NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 support

* add power tracking support

* add 802.11ac beamformee support

* add set_bitrate_mask support

* add phy_info debugfs to show Tx/Rx physical status

* add RFE type 3 support for 8822b

ath10k

* add support for hardware rfkill on devices where firmware supports it

rtl8xxxu

* add bluetooth co-existence support for single antenna

iwlwifi

* Revamp the debugging infrastructure

2ce113de31 mac80211: simplify TX aggregation start
There really is no need to make drivers call the
ieee80211_start_tx_ba_cb_irqsafe() function and then
schedule the worker if all we want is to set a bit.

Add a new return value (that was previously considered
invalid) to indicate that the driver is immediately
ready for the session, and make drivers use it. The
only drivers that remain different are the Intel ones
as they need to negotiate more with the firmware.
