1d27e3e225 timer: Remove expires and data arguments from DEFINE_TIMER
Drop the arguments from the macro and adjust all callers with the

  perl -pi -e 's/DEFINE_TIMER\((.*), 0, 0\);/DEFINE_TIMER($1);/g;' \
    $(git grep DEFINE_TIMER | cut -d: -f1 | sort -u | grep -v timer.h)

2eabc84d2f iwlwifi: mvm: only send LEDS_CMD when the FW supports it
The LEDS_CMD command is only supported in some newer FW versions
(e.g. iwlwifi-8000C-31.ucode), so we can't send it to older versions
(such as iwlwifi-8000C-27.ucode).

To fix this, check for a new bit in the FW capabilities TLV that tells
when the command is supported.

Note that the current version of -31.ucode in linux-firmware.git
(31.532993.0) does not have this capability bit set, so the LED won't
work, even though this version should support it.  But we will update
this firmware soon, so it won't be a problem anymore.

6d62269283 rtlwifi: btcoexist: Fix antenna selection code
In commit 87d8a9f352 ("rtlwifi: btcoex: call bind to setup btcoex"),
the code turns on a call to exhalbtc_bind_bt_coex_withadapter(). This
routine contains a bug that causes incorrect antenna selection for those
HP laptops with only one antenna and an incorrectly programmed EFUSE.
These boxes are the ones that need the ant_sel module parameter.

parameter ant_sel is used to select the auxilary antenna. The error is
that the antenna selection is not checked when writing the antenna

9de981f507 mac80211_hwsim: Use proper TX power
In struct ieee80211_tx_info, control.vif pointer and rate_driver_data[0]
falls on the same place, depending on the union usage.
During the whole TX process, the union is referred to as a control struct,
which holds the vif that is later used in the tx flow, especially in order
to derive the used tx power.
Referring direcly to rate_driver_data[0] and assigning a value to it,
overwrites the vif pointer, hence making all later references irrelevant.
Moreover, rate_driver_data[0] isn't used later in the flow in order to
retrieve the channel that it is pointing to.

393b706cf2 ath10k: configure and enable the wakeup capability
ACPI will rely on device driver to tell it if the device could support
wakeup function when system in D3 state.

This has caused some platform can't support remote wakeup correctly,
because the ACPI wakeup GPE is not enabled, hence registers the .set_wakeup
callback to handle it if device supports wakeup.

Tested with QCA6174 hw3.0, firmware ('WLAN.RM.4.4.1-00008-QCARMSWP-1')

32faa3f0ee ath10k: add the PCI PM core suspend/resume ops
The actual PCI suspend/resume in ath10k has been handled in wow.c,
but in the case of the device doesn't support remote wakeup,
the .hif_suspend() and .hif_resume() will never be handled.

  ath10k_wow_op_suspend()
  {
	if (WARN_ON(!test_bit(ATH10K_FW_FEATURE_WOWLAN_SUPPORT,
		    ar->running_fw->fw_file.fw_features))) {
		ret = 1;
		goto exit;
	}

	....

	ret = ath10k_hif_suspend(ar);
  }

So register the PCI PM core to support the suspend/resume if the device
doesn't support remote wakeup.

c0cc00f250 ath10k: activate user space firmware loading again
In commit 9f5bcfe933 ("ath10k: silence firmware file probing
warnings") the firmware loading was changed from request_firmware() to
request_firmware_direct() to silence some warnings in case it fails.
request_firmware_direct() directly searches in the file system only and
does not send a hotplug event to user space in case it could not find
the firmware directly.
In LEDE we use a user space script to extract the calibration data from
the flash memory which gets triggered by the hotplug event. This way the
firmware gets extracted from some vendor specific partition when the
driver requests this firmware. This mechanism does not work any more
after this change.

c9353bf483 ath10k: fix napi_poll budget overflow
In napi_poll, the budget number is used to control the amount of packets
we should handle per poll to balance the resource in the system.

In the list of the amsdu packets reception, we check if there is budget
count left and handle the complete list of the packets, that it will have
chances the very last list will over the budget leftover.

So adding one more parameter - budget_left, this would help while
traversing the list to avoid handling more than the budget given.

eb045e6e03 iwlwifi: mvm: Avoid deferring non bufferable frames
Use bcast station for all non bufferable frames on AP and AD-HOC.

The host is no longer aware of STAs PS status because of buffer
station offload, so we can't rely on mac80211 to toggle on
IEEE80211_TX_CTL_NO_PS_BUFFER bit.

A possible issue with buffering such frames, beside the obvious spec
violation, is when a station disconnects while in PS but the AP isn't
aware of that. In such scenarios the AP won't be able to send probe
responses or auth frames so the STA won't be able to reconnect and
the AP will have a queue hang.

d382b9c007 wlcore: add missing nvs file name info for wilink8
The following commits:
commit c815fdebef ("wlcore: spi: Populate config firmware data")
commit d776fc86b8 ("wlcore: sdio: Populate config firmware data")

Populated the nvs entry for wilink6 and wilink7 only while it is
still needed for wilink8 as well.
This broke user space backward compatibility when upgrading from older
kernels, as the alternate mac address would not be read from the nvs that
is present in the file system (lib/firmware/ti-connectivity/wl1271-nvs.bin)
causing mac address change of the wlan interface.

This patch fix this and update the structure field with the same default
nvs file name that has been used before.

In addition, some distros hold a default wl1271-nvs.bin in the file
system with a bogus mac address (deadbeef...) that overrides the mac
address that is stored inside the device.
Warn users about this bogus mac address and use the internal mac address
