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.

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.

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-guideline...
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.
