mwifiex: memory corruption in mwifiex_tdls_add_vht_capab()
There is a typo here because the names are confusingly similar. The
intent was sizeof(struct ieee80211_vht_cap) (size 12) but sizeof(struct
ieee80211_ht_cap) (size 32) was used.
Anway, it's cleaner to just specify the variable instead of the type.

iwlwifi: mvm: prepare infrastructure for more TLV flags
We use the TLV flags as a handshake between the firmware
and the driver. These flags allow the firmware to advertise
its capabilities and API version.
Since we are running short of bits, we add a new
infrastructure which is more scalable, yet backward
compatible.
We make now the difference between API changes and the
capabilities. Both can have an index which allows to scale
at will.

iwlwifi: nvm: remove reading valid antennas from NVM
These values aren't used as the firmware values should be used,
so reading them is pointless and hides potential errors when
somebody uses these values. Leave them zero to make it clearer
that they can't be used. We can't remove the struct members as
the DVM driver does read the values from EEPROM/OTP and the
structure is shared between drivers.

cfg80211: remove radar requirements check from cfg80211_can_use_iftype_chan()
We don't have to double check whether the parameters passed to
cfg80211_can_use_iftype_chan() are correct. We should just make sure
they *are* when we call this function.
Remove the radar_detect argument check in
cfg80211_can_use_iftype_chan() to simplify the code.

mac80211: allow drivers to request SMPS off

cfg80211: docbook: fix small formatting error
docbook (or one of its friends) gets confused with semi-colons in the

marking a new section in the description of addr_mask in wiphy struct.
Prevent this by using hyphens instead of semi-colons in the mask

cfg80211: regulatory: introduce NL80211_RRF_AUTO_BW rule flag
Introduce NL80211_RRF_AUTO_BW rule flag. If this flag set
maximum available bandwidth should be calculated base on
contiguous rules and wider channels will be allowed to cross
multiple contiguous/overlapping frequency ranges.
In case of old kernels maximum bandwidth from regulatory
rule will be used, while there is no NL80211_RRF_AUTO_BW flag.
This fixes the previous commit 9752482083066af7ac18a5ca376f
("cfg80211: regulatory introduce maximum bandwidth calculation")
which was found to be a problem for userspace API compatibility.

Bluetooth: Increase minor version of core module
With the addition of Resolvable Private Address (RPA) resolution
support for Bluetooth Low Energy connections, it makes sense to
increase the minor version of the Bluetooth core module.
The module version is not used anywhere, but it gives a nice extra
hint for debugging purposes.
