The connectors may be registered after the ports, so the "connector" links need to be created for the ports also when ever a new connector gets registered.

2021-04-09usb: Iterator for portsHeikki Krogerus
Introducing usb_for_each_port(). It works the same way as usb_for_each_dev(), but instead of going through every USB device in the system, it walks through the USB ports in the system.

2021-04-09usb: typec: Port mapping utilityHeikki Krogerus
Adding functions that can be used to link/unlink ports - USB ports, TBT3/USB4 ports, DisplayPorts and so on - to the USB Type-C connectors they are attached to inside a system. The symlink that is created for the port device is named "connector". Initially only ACPI is supported. ACPI port object shares the _PLD (Physical Location of Device) with the USB Type-C connector that it's attached to.

tcpm_pd_select_pps_apdo overwrites port->pps_data.min_volt, port->pps_data.max_volt, port->pps_data.max_curr even before port partner accepts the requests. This leaves incorrect values in current_limit and supply_voltage that get exported by "tcpm-source-psy-".

With current implementation the port power is being disabled, which is not required by the programming guide. Also, if there is a system which works only in "DWC2_POWER_DOWN_PARAM_NONE" (clock gating) mode the current implementation does not set Gate hclk bit in pcgctl register.

2021-04-09staging: comedi: Kconfig: Fix COMEDI_TESTS_NI_ROUTES selectionsIan Abbott
The COMEDI_TESTS_NI_ROUTES option currently selects NI_ROUTING, which doesn't exist. It should be selecting COMEDI_NI_ROUTING. Fix it. Selecting COMEDI_TESTS_NI_ROUTES without COMEDI_NI_ROUTING resulted in the following build errors: ERROR: modpost: "ni_lookup_route_register" [drivers/staging/comedi/drivers/tests/ni_routes_test.ko] undefined!

2021-04-09media: gscpa/stv06xx: fix memory leakHans Verkuil
For two of the supported sensors the stv06xx driver allocates memory which is stored in sd->sensor_priv. This memory is freed on a disconnect, but if the probe() fails, then it isn't freed and so this leaks memory. Add a new probe_error() op that drivers can use to free any allocated memory in case there was a probe failure. Thanks to Pavel Skripkin <paskripkin@gmail.com> for discovering the cause of the memory leak.
