The recent change to the PM QoS framework to introduce a proper
no constraint value overlooked to handle the devices which don't
implement PM QoS OPS. Runtime PM is one of the more severely
impacted subsystems, failing every attempt to runtime suspend
a device. This leads into some nasty second level issues like
probe failures and increased power consumption among other
things.
Fix this by adding a proper return value for devices that don't
implement PM QoS.

Thorsten reported on <fa6e3ee2-91b5-a54b-afe3-87f30aac7a48@leemhuis.info> that
commit c9353bf483d3 made ath10k unstable with QCA6174 on his Dell XPS13 (9360)
with an error message:
ath10k_pci 0000:3a:00.0: failed to extract amsdu: -11
It only seemed to happen with certain APs, not all, but when it happened the
only way to get ath10k working was to switch the wifi off and on with a hotkey.
As this commit made things even worse (a warning vs breaking the whole
connection) let's revert the commit for now and while the issue is being fixed.

Rx data frames notified through HTT_T2H_MSG_TYPE_RX_IND and
HTT_T2H_MSG_TYPE_RX_FRAG_IND expect PN/TSC check to be done
on host (mac80211) rather than firmware. Rebuild cipher header
in every received data frames (that are notified through those
HTT interfaces) from the rx_hdr_status tlv available in the
rx descriptor of the first msdu. Skip setting RX_FLAG_IV_STRIPPED
flag for the packets which requires mac80211 PN/TSC check support
and set appropriate RX_FLAG for stripped crypto tail. Hw QCA988X,
QCA9887, QCA99X0, QCA9984, QCA9888 and QCA4019 currently need the
rebuilding of cipher header to perform PN/TSC check for replay
attack.
Please note that removing crypto tail for CCMP-256, GCMP and GCMP-256 ciphers
in raw mode needs to be fixed. Since Rx with these ciphers in raw
mode does not work in the current form even without this patch and
removing crypto tail for these chipers needs clean up, raw mode related
issues in CCMP-256, GCMP and GCMP-256 can be addressed in follow up
patches.

A previous commit changed the argument list of gpio_fan_get_of_data(),
removing the "struct *dev" argument and retrieving it instead from the
gpio_fan_data structure. The "dev" entry of gpio_fan_data was then
dereferenced to access the of_node field, leading to a kernel panic
during the probe as the "dev" entry of the gpio_fan_data structure was
not filled yet.
Fix this by setting fan_data->dev before calling gpio_fan_get_of_data().

This converts the GPIO fan driver to use GPIO descriptors. This way
we avoid indirection since the gpiolib anyway just use descriptors
inside, and we also get rid of explicit polarity handling: the
descriptors internally knows if the line is active high or active
low.

The "ctrl" and "num_ctrl" entries in the state container struct is

We are not passing the platform data struct into the driver from the

of first populating the platform data struct and assigning the result
into the same variables in the state container (struct gpio_fan_data)

The previous value reduced the time required to determine
the fan value, however, it's also used as the final timeout
mechanism. The prevous value would work for any fan speed
greater than around 3k RPM. This increased value, lets the fan
speeds return quickly but will wait longer to handle speeds below 3k
RPM.
Testing: this value was determined through experimentation on the ast2400
on the Quanta-q71l. This configurations runs 8 fans attached to the
controller.

After finding out there are active users of this sensor I noticed:
- It has a single PXA27x board file using the platform data
- The platform data is only used to carry two GPIO pins, all other
fields are unused
- The driver does not use GPIO descriptors but the legacy GPIO
API
I saw we can swiftly fix this by:
- Killing off the platform data entirely
- Define a GPIO descriptor lookup table in the board file
- Use the standard devm_gpiod_get() to grab the GPIO descriptors
from either the device tree or the board file table.
This compiles, but needs testing.

The pmbus core may call read/write word data functions with a page value
of -1, intending to perform the operation without setting the page.
However, the read/write word data functions accept only unsigned 8-bit
page numbers, and therefore cannot check for negative page number to
avoid setting the page. This results in setting the page number to 0xFF.
This may result in errors or undefined behavior of some devices
(specifically the ir35221, which allows the page to be set to 0xFF,
but some subsequent operations to read registers may fail).
Switch the pmbus_set_page page parameter to an integer and perform the
check for negative page there. Make read/write functions consistent in
accepting an integer page number parameter.

====================
net_sched: fix races with RCU callbacks
Recently, the RCU callbacks used in TC filters and TC actions keep
drawing my attention, they introduce at least 4 race condition bugs:
1. A simple one fixed by Daniel:
commit c78e1746d3ad7d548bdf3fe491898cc453911a49
Author: Daniel Borkmann <daniel@iogearbox.net>
Date: Wed May 20 17:13:33 2015 +0200
net: sched: fix call_rcu() race on classifier module unloads
2. A very nasty one fixed by me:
commit 1697c4bb5245649a23f06a144cc38c06715e1b65
Author: Cong Wang <xiyou.wangcong@gmail.com>
Date: Mon Sep 11 16:33:32 2017 -0700
net_sched: carefully handle tcf_block_put()
3. Two more bugs found by Chris:
https://patchwork.ozlabs.org/patch/826696/
https://patchwork.ozlabs.org/patch/826695/
Usually RCU callbacks are simple, however for TC filters and actions,
they are complex because at least TC actions could be destroyed
together with the TC filter in one callback. And RCU callbacks are
invoked in BH context, without locking they are parallel too. All of
these contribute to the cause of these nasty bugs.
Alternatively, we could also:
a) Introduce a spinlock to serialize these RCU callbacks. But as I
said in commit 1697c4bb5245 ("net_sched: carefully handle
tcf_block_put()"), it is very hard to do because of tcf_chain_dump().
Potentially we need to do a lot of work to make it possible (if not
impossible).
b) Just get rid of these RCU callbacks, because they are not
necessary at all, callers of these call_rcu() are all on slow paths
and holding RTNL lock, so blocking is allowed in their contexts.
However, David and Eric dislike adding synchronize_rcu() here.
As suggested by Paul, we could defer the work to a workqueue and
gain the permission of holding RTNL again without any performance
impact, however, in tcf_block_put() we could have a deadlock when
flushing workqueue while hodling RTNL lock, the trick here is to
defer the work itself in workqueue and make it queued after all
other works so that we keep the same ordering to avoid any
use-after-free. Please see the first patch for details.
Patch 1 introduces the infrastructure, patch 2~12 move each
tc filter to the new tc filter workqueue, patch 13 adds
an assertion to catch potential bugs like this, patch 14
closes another rcu callback race, patch 15 and patch 16 add
new test cases.

In this patchset, we fixed a tc bug. This patch adds the test case
that reproduces the bug. To run this test case, user should specify
an existing NIC device:
# sudo ./tdc.py -d enp4s0f0
This test case belongs to category "flower". If user doesn't specify
a NIC device, the test cases belong to "flower" will not be run.
In this test case, we create 1M filters and all filters share the same
action. When destroying all filters, kernel should not panic. It takes
about 18s to run it.
