743b2b7e08 staging: vt6656: Simplify RX finding bit rates
The bit rate can be found by multiplying the rate value by 5.

Use rx_bitrate to compared to sband bitrates removing the need
to find it by hw_value.

4d1356ac12 staging: most: net: fix buffer overflow
If the length of the socket buffer is 0xFFFFFFFF (max size for an
unsigned int), then payload_len becomes 0xFFFFFFF1 after subtracting 14
(ETH_HLEN).  Then, mdp_len is set to payload_len + 16 (MDP_HDR_LEN)
which overflows and results in a value of 2.  These values for
payload_len and mdp_len will pass current buffer size checks.

This patch checks if derived from skb->len sum may overflow.

The check is based on the following idea:

For any `unsigned V1, V2` and derived `unsigned SUM = V1 + V2`,
`V1 + V2` overflows iif `SUM < V1`.

7b2d7faa09 Second set of new device support, features and minor fixes for IIO in the 5.6 cycle
Just a small set this time.
 
 As we are very near the merge window, I've rolled a few fixes in here
 rather than adding noise just before release.  A short delay here will
 do little harm.
 
 New device support
 * adis16480
   - Add support for adis16490. After earlier rework this is simple ID plus
     chip info.
 
 Features
 * kxcjk1013
   - mount matrix support.
 * lsm_6dsx
   - mount matrix support.
 
 Cleanups / minor or late breaking fixes
 * ad7124
   - add support to ad-sigma-delta and use it in this driver to allow
     the the interrupt type to be IRQF_TRIGGER_LOW unlike most other devices
     using this framework.
 * adis
   - use delay structure now available in SPI to handle transfer delays
   - introduce a timeouts structure to allow support of new devices
 * ak8975
   - drop platform data support.  No one is using it and it adds complexity.
   - use device_get_match_data rather than open coding much the same thing.
 * dht11
   - drop meaningless todo
 * at91-samad2_adc
   - switch to dma_request_chan
 * altas-sensor
   - add a helper function to compute number of channels.  Needed for new device
     support that is under review.
 * bma400
   - add a lower bound check on scale.
 * inv_mpu6050
   - add support for temperature data in the fifos for all chips.
   - support an odd situation where a board supports only interrupt triggering
     on both edges.
 * st_lsm6dsx
   - check and handle potential error return.
 * st_sensors
   - fix some values for the LSM9DS0 which is ever so slightly different from
     other devices using the same whoami value.
   - switch over to generic functions from dt ones, avoiding need for separate
     ACPI support.
 * stm32-adc
   - switch to dma_request_chan
   - suppress an error print in deferred probe case.
 * stm32-dac
   - drop private data structure element for reset controller as only used in

a3c529a835 staging: wfx: simplify handling of IEEE80211_TX_CTL_SEND_AFTER_DTIM
When mac80211 ask for a frame to be sent after a DTIM, driver should:
  1. Update TIM with multicast bit set (using update_ie). This function
     can be called whenever.
  2. Keep buffered all frames marked "after dtim"
  3. When it receive a suspend_resume indication (see
     wfx_suspend_resume_mc()), send all the buffered frames. This
     indication is sent by the firmware 4ms before the dtim.
  4. If one of the frames returns status "REQUEUE", it means that the
     DTIM period was ended before to be able to send the frame.
  5. When all the buffered frames were sent or if DTIM period was ended,
     driver should update the TIM with multicast bit reset.

All the mess with the asynchronous works can be dropped.

b5d4d98ec8 staging: wfx: firmware never return PS status for stations
At the beginning, firmware could send suspend_resume indication to
notify that a station wake up or sleep down. However, mac80211 already
handles power save status of stations and this behavior has been removed
from the firmware. So now, when suspend_resume indication is received,
it is always to notify that a DTIM is about to be sent.

So, it is possible to simply wfx_suspend_resume().

sta_notify when a ps-poll is received. So pspoll_mask is useless and
sta_alseep_mask is sufficient.

wfx_tx_get_tid() was used as a wrapper around ieee80211_get_tid(). It
did sometime return WFX_MAX_TID to ask to upper layers to not include
the frame in "buffered" counter. The objective of this behavior is not
clear, but tests has shown that wfx_tx_get_tid() can be replaced by
ieee80211_get_tid() without any regressions.

BTW, it is not necessary to save the tid in tx_rpiv since it can be
retrieved from the 802.11 header.

d6aeba575f staging: wfx: simplify the link-id allocation
The "link-id" is a slot number provided to the chip. A link-id is
allocated to every station associated with the chip (mainly when the
chip is in AP mode). It is more or less the same thing than the
association ID, but it is limited to 14 values.

Firmware uses the link-id to track the power save status of the
stations.

The current code try to associate a link-id as soon as data are
exchanged with station. It is far easier to rely on sta_add() and
sta_remove().

Until now the value WFX_LINK_ID_NO_ASSOC, was only used when no more
link-id was available. Now, we also use this value for
not-yet-associated stations (that was its primary behavior).

Argument provided to wfx_set_tim_impl() is always wvif->aid0_bit_set and
there is no reason to provide another argument.

Also rename wfx_set_tim_impl() into wfx_update_tim() to reflect the new
behavior.

76b5c2ce46 staging: wfx: fix bss_loss
wfx_tx_confirm_cb()  retrieves the station associated with a frame using
the MAC address from the 802.11 header. In the other side wfx_tx()
retrieves the station using sta field from the ieee80211_tx_control
argument.

In wfx_cqm_bssloss_sm(), wfx_tx() was called directly without valid sta
field, but with a valid MAC address in 802.11 header. So there the
processing of this packet was unbalanced and may produce weird bugs.

wfx_conf_tx() is called for each queue. On every call, the function
updates UAPSD mask and PM mode for all queues. It is a pity since the
UAPSD configuration very rarely changes and it makes exchanges between
the host and the chip more difficult to track.

This patch avoid to update UAPSD and Power Mode in most usual cases.

f98138a16f staging: wfx: with multiple vifs, force PS only if channels differs
When multiple vif are in use (the only supported configuration is one
station and one AP), the driver force power save flag on station.
This behavior allows the station to leave the station channel and make
its business on AP channel.

However, this has a big impact on station performances (especially since
only legacy PS is supported).

When both vifs use the same channel, it is not necessary to keep this
restriction. This greatly improve station performances.

mac80211 and the device are both able to control power-save per vif.
But, the current code retrieve power-save from wfx_config(). So, it does
not allow to setup power-save independently for each vif. Driver just
has to rely on wfx_bss_info_changed() instead of wfx_config().

wfx_config() has nothing to do anymore, but we keep it since it is
mandatory for mac80211.
