[ Upstream commit cacfddf82baf1470e5741edeecb187260868f195 ]
In mac80211_hwsim, the probe_req frame is created and sent while
scanning. It is sent with ieee80211_tx_info which is not initialized.
Uninitialized ieee80211_tx_info can cause problems when using
mac80211_hwsim with wmediumd. wmediumd checks the tx_rates field of
ieee80211_tx_info and doesn't relay probe_req frame to other clients
even if it is a broadcasting message.
Call ieee80211_tx_prepare_skb() to initialize ieee80211_tx_info for
the probe_req that is created by hw_scan_work in mac80211_hwsim.

[ Upstream commit 9495b9b31abe525ebd93da58de2c88b9f66d3a0e ]
The CLKT register contains at poweron 0x40, which at our typical 100kHz
bus rate means .64ms. But there is no specified limit to how long devices
should be able to stretch the clocks, so just disable the timeout. We
still have a timeout wrapping the entire transfer.

[ Upstream commit a6d78661dc903d90a327892bbc34268f3a5f4b9c ]
The current rt5668_jack_detect_handler() assumes the component
and card will always show up and implements an infinite usleep
loop waiting for them to show up.
This does not hold true if a codec interrupt (or other
event) occurs when the card is unbound. The codec driver's
remove or shutdown functions cannot cancel the workqueue due
to the wait loop. As a result, code can either end up blocking
the workqueue, or hit a kernel oops when the card is freed.
Fix the issue by rescheduling the jack detect handler in
case the card is not ready. In case card never shows up,
the shutdown/remove/suspend calls can now cancel the detect
task.

From: José Expósito <jose.exposito89@gmail.com>
[ Upstream commit 37ef4c19b4c659926ce65a7ac709ceaefb211c40 ]
Buttonpads are expected to map the INPUT_PROP_BUTTONPAD property bit
and the BTN_LEFT key bit.
As explained in the specification, where a device has a button type
value of 0 (click-pad) or 1 (pressure-pad) there should not be
discrete buttons:
https://docs.microsoft.com/en-us/windows-hardware/design/component-guidelines/touchpad-windows-precision-touchpad-collection#device-capabilities-feature-report
However, some drivers map the BTN_RIGHT and/or BTN_MIDDLE key bits even
though the device is a buttonpad and therefore does not have those
buttons.
This behavior has forced userspace applications like libinput to
implement different workarounds and quirks to detect buttonpads and
offer to the user the right set of features and configuration options.
For more information:
https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/726
In order to avoid this issue clear the BTN_RIGHT and BTN_MIDDLE key
bits when the input device is register if the INPUT_PROP_BUTTONPAD
property bit is set.
Notice that this change will not affect udev because it does not check
for buttons. See systemd/src/udev/udev-builtin-input_id.c.

When cifs_get_root() fails during cifs_smb3_do_mount() we call
deactivate_locked_super() which eventually will call delayed_free() which
will free the context.
In this situation we should not proceed to enter the out: section in
cifs_smb3_do_mount() and free the same resources a second time.

The PREEMPT_RT patchset does not use do_softirq() function thus trying
to filter for do_softirq fails for such kernel:
echo do_softirq
ftracetest: 81: echo: echo: I/O error
Choose some other visible function for the test. The function does not
have to be actually executed during the test, because it is only testing
filter API interface.

This needs -rt patch even on mainline, right?
It is certainly not needed in -stable branches.

I believe this does not fix a bug and so is not suitable for stable.
