wl3501_cs: Replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

libertas: Use new structure for SPI transfer delays
In a recent change to the SPI subsystem [1], a new `delay` struct was added
to replace the `delay_usecs`. This change replaces the current
`delay_usecs` with `delay` for this driver.
The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure
that both `delay_usecs` & `delay` are used (in this order to preserve
backwards compatibility).

mwifiex: set needed_headroom, not hard_header_len
hard_header_len provides limitations for things like AF_PACKET, such
that we don't allow transmitting packets smaller than this.
needed_headroom provides a suggested minimum headroom for SKBs, so that
we can trivally add our headers to the front.
The latter is the correct field to use in this case, while the former
mostly just prevents sending small AF_PACKET frames.
In any case, mwifiex already does its own bounce buffering [1] if we
don't have enough headroom, so hints (not hard limits) are all that are
needed.
This is the essentially the same bug (and fix) that brcmfmac had, fixed
in commit

were reported under the same sysfs directory for pcie device, e.g.:
$ ls /sys/class/net/wlan0/device/net/

It turns out that such behavior may confuse various users of wireless

- OpenWRT configuration scripts
Suggested solution is to add an intermediate virtual platform device

ftgmac100: Remove redundant judgement
In this function, ftgmac100_probe() can be triggered only
if the platform_device and platform_driver matches, so the
judgement at the beginning is redundant.

ath9k: Handle txpower changes even when TPC is disabled
When TPC is disabled IEEE80211_CONF_CHANGE_POWER event can be handled to
reconfigure HW's maximum txpower.
This fixes 0dBm txpower setting when user attaches to an interface for
the first time with the following scenario:
ieee80211_do_open()
ath9k_add_interface()
ath9k_set_txpower() /* Set TX power with not yet initialized
sc->hw->conf.power_level */
ieee80211_hw_config() /* Iniatilize sc->hw->conf.power_level and
raise IEEE80211_CONF_CHANGE_POWER */
ath9k_config() /* IEEE80211_CONF_CHANGE_POWER is ignored */
This issue can be reproduced with the following:
$ modprobe -r ath9k
$ modprobe ath9k
$ wpa_supplicant -i wlan0 -c /tmp/wpa.conf &
$ iw dev /* Here TX power is either 0 or 3 depending on RF chain */
$ killall wpa_supplicant
$ iw dev /* TX power goes back to calibrated value and subsequent
calls will be fine */

ath5k: Add proper dependency for ATH5K_AHB
The CONFIG_ATH5K_AHB could be enabled on ATH25 system without enabling
ATH5K driver itself. This does not make sense because CONFIG_ATH5K_AHB
controls object build within drivers/net/wireless/ath/ath5k/ so enabling
it without CONFIG_ATH5K brings nothing.
Add proper dependency to CONFIG_ATH5K_AHB.

ath11k: add thermal sensor device support
Temperature sensor generates electrical analog voltage from temperature
of each chain. The analog voltage is converted to digital value through
ADC. For reading temperature values fom user space, hw monitoring device
is used.
Whenever the user requests for current temperature, the driver sends WMI
command and wait for response. For reading temperature,
