Alexandru Ardelean f091d7c5fe iio: adc: at91_adc: add Kconfig dep on the OF symbol and remove of_match_ptr()
This tries to solve a warning reported by the lkp bot:

                                    ^
   1 warning generated.

This warning has appeared after the AT91_ADC driver compilation has been
enabled via the COMPILE_TEST symbol dependency.

The warning is caused by the 'of_match_ptr()' helper which returns NULL if
OF is undefined. This driver should build only for device-tree context, so
a dependency on the OF Kconfig symbol has been added.
Also, the usage of of_match_ptr() helper has been removed since it
shouldn't ever return NULL (because the driver should not be built for the
non-OF context).

Alexandru Ardelean 3e4ef8e8ce iio: adc: at91_adc: const-ify some driver data
The main intent is to get rid of the cast for the void-pointer returned by
of_device_get_match_data().

This requires const-ifying the 'caps' and 'registers' references on the
at91_adc_state struct.

The caps can be obtained also from the old platform_data (in the
at91_adc_probe_pdata() function), but that cast is not touched in this
patch, since the old platform_data should be removed/cleaned-away.
Also, that cast deals with converting a kernel_ulong_t type to a pointer.
So, updating that cast doesn't yield any benefit.

Jérôme Pouiller 0d2dfdb885 staging: wfx: fix QoS priority for slow buses
The device is in charge of respecting the QoS constraints. The driver
have to ensure that all the queues contain data and the device choose
the right queue to send.

The things starts to be more difficult when the bandwidth of the bus is
lower than the bandwidth of the WiFi. The device quickly sends the
frames of the highest priority queue. Then, it starts to send frames
from a lower priority queue. Though, there are still some high priority
frames waiting in the driver.

To work around this problem, this patch add some priorities to each
queue. The weigh of the queue was (roughly) calculated experimentally by
checking the speed ratio of each queue when the bus does not limit the
traffic:
    - Be/Bk -> 20Mbps/10Mbps
    - Vi/Be -> 36Mbps/180Kbps
    - Vo/Be -> 35Mbps/600Kbps
    - Vi/Vo -> 24Mbps/12Mbps

So, if we fix the weigh of the Background to 1, the weight of Best
Effort should be 2. The weight of Video should be 116. However, since
there is only 32 queues, it make no sense to use a value greater than
64[1]. And finally, the weight of the Voice is set to 128.

[1] Because of this approximation, with very slow bus, we can still
observe frame starvation when we measure the speed ratio of Vi/Be. It is
around 35Mbps/1Mbps (instead of 36Mbps/180Kbps). However, it is still in
accepted error range.

Jérôme Pouiller 4fd1241778 staging: wfx: fix BA sessions for older firmwares
Firmwares with API < 3.6 do not forward DELBA requests. Thus, when a
Block Ack session is restarted, the reordering buffer is not flushed and
the received sequence number is not contiguous. Therefore, mac80211
starts to wait some missing frames that it will never receive.

This patch disables the reordering buffer for old firmware. It is
harmless when the network is unencrypted. When the network is encrypted,
the non-contiguous frames will be thrown away by the TKIP/CCMP replay
protection. So, the user will observe some packet loss with UDP and
performance drop with TCP.

Jérôme Pouiller 8d350c14ee staging: wfx: fix handling of MMIC error
As expected, when the device detect a MMIC error, it returns a specific
status. However, it also strip IV from the frame (don't ask me why).

So, with the current code, mac80211 detects a corrupted frame and it
drops it before it handle the MMIC error. The expected behavior would be
to detect MMIC error then to renegotiate the EAP session.

So, this patch correctly informs mac80211 that IV is not available. So,
mac80211 correctly takes into account the MMIC error.

Dan Carpenter 8750de90ac staging: vchiq: Fix list_for_each exit tests
After a list_for_each_entry() loop, the list iterator is always non-NULL
so these conditions don't work.  If the "waiter" is not found then this
results in an out of bounds access.

I have fixed it by introducing a new "found" variable.  In one case, I
used an else statement for readability.
