+Subject: cifs: fix double free race when mount fails in cifs_get_root()
+
+From: Ronnie Sahlberg <lsahlber@redhat.com>
+
+[ Upstream commit 3d6cc9898efdfb062efb74dc18cfc700e082f5d5 ]
+
+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.

+
+From: Eric Anholt <eric@anholt.net>
+
+[ 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.

+Subject: Input: clear BTN_RIGHT/MIDDLE on buttonpads
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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.
+
+List of known affected hardware:
+
+ - Chuwi AeroBook Plus
+ - Chuwi Gemibook
+ - Framework Laptop
+ - GPD Win Max
+ - Huawei MateBook 2020
+ - Prestigio Smartbook 141 C2

+
+From: JaeMan Park <jaeman@google.com>
+
+[ 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.
