msm: camera: Fix crash in ispif release

There is a BUG_ON in ispif release function for
ispif base address. but in case of just open and close
of ispif subdevice leads to ispif base NULL.

BUG_ON is removed and proper error is added in ispif
release function to fix the issue.

cfg80211: pass station supported channel and oper class info

The information of the peer's supported channels and supported operating
classes are required for the driver to perform TDLS off channel
operations. This commit enhances the function nl80211_(new)set_station
to pass this information of the peer to the driver.

nl80211: vendor command support

Add support for vendor-specific commands to nl80211. This is
intended to be used for really vendor-specific functionality
that can't be implemented in a generic fashion for any reason.
It's *NOT* intended to be used for any normal/generic feature
or any optimisations that could be implemented across drivers.
Currently, only vendor commands (with replies) are supported,
no dump operations or vendor-specific notifications.
Also add a function wdev_to_ieee80211_vif() to mac80211 which
is needed for mac80211-based drivers wanting to implement any
vendor commands.

nl80211: support vendor-specific events

In addition to vendor-specific commands, also support vendor-specific
events. These must be registered with cfg80211 before they can be used.
They're also advertised in nl80211 in the wiphy information so that
userspace knows can be expected. The events themselves are sent on a
new multicast group called "vendor".

cfg80211: Add support for QoS mapping

This allows QoS mapping from external networks to be implemented as
defined in IEEE Std 802.11-2012, 10.24.9. APs can use this to advertise
DSCP ranges and exceptions for mapping frames to a specific UP over
Wi-Fi.

The payload of the QoS Map Set element (IEEE Std 802.11-2012, 8.4.2.97)
is sent to the driver through the new NL80211_ATTR_QOS_MAP attribute to
configure the local behavior either on the AP (based on local
configuration) or on a station (based on information received from the
AP).

cfg80211: Allow BSS hint to be provided for connect

This clarifies the expected driver behavior on the older
NL80211_ATTR_MAC and NL80211_ATTR_WIPHY_FREQ attributes and adds a new
set of similar attributes with _HINT postfix to enable use of a
recommendation of the initial BSS to choose. This can be helpful for
some drivers that can avoid an additional full scan on connection
request if the information is provided to them (user space tools like
wpa_supplicant already has that information available based on earlier
scans).

In addition, this can be used to get more expected behavior for cases
where a specific BSS should be picked first based on operations like
Interworking network selection or WPS. These cases were already easily
addressed with drivers that leave BSS selection to user space, but there
was no convenient way to do this with drivers that take care of BSS
selection internally without using the NL80211_ATTR_MAC which is not
really desired since it is needed for other purposes to force the
association to remain with the same BSS.

cfg80211: Advertise maximum associated STAs in AP mode

This allows drivers to advertise the maximum number of associated
stations they support in AP mode (including P2P GO). User space
applications can use this for cleaner way of handling the limit (e.g.,
hostapd rejecting IEEE 802.11 authentication without manual
configuration of the limit) or to figure out what type of use cases can
be executed with multiple devices before trying and failing.

cfg80211: Pass TDLS peer capability information in tdls_mgmt

While framing the TDLS Setup Confirmation frame, the driver needs to
know if the TDLS peer is VHT/HT/WMM capable and thus shall construct
the VHT/HT operation / WMM parameter elements accordingly. Supplicant
determines if the TDLS peer is VHT/HT/WMM capable based on the
presence of the respective IEs in the received TDLS Setup Response frame.

The host driver should not need to parse the received TDLS Response
frame and thus, should be able to rely on the supplicant to indicate
the capability of the peer through additional flags while transmitting
the TDLS Setup Confirmation frame through tdls_mgmt operations.

mac80211: implement HS2.0 gratuitous ARP/unsolicited NA dropping

Taking the gratuitous ARP/unsolicited NA detection code from
mwifiex (but fixing it up to not have read-after-skb-end bugs),
implement the ability for userspace to request the behaviour
required by HS2.0 to drop gratuitous ARP and unsolicited NA
frames when proxy ARP service is enabled on the AP. Since this
behaviour is only mandatory for HS2.0 and may not always be
desired, make it optional - modify cfg80211/nl80211 for that.

rcu: Add a module parameter to force use of expedited RCU primitives

There have been some embedded applications that would benefit from
use of expedited grace-period primitives.  In some ways, this is
similar to synchronize_net() doing either a normal or an expedited
grace period depending on lock state, but with control outside of
the kernel.

This commit therefore adds rcu_expedited boot and sysfs parameters
that cause the kernel to substitute expedited primitives for the
normal grace-period primitives.
