Pull USB / Thunderbolt updates from Greg KH: "Here is the "big" set of USB and Thunderbolt driver changes for 5.18-rc1. For the most part it's been a quiet development cycle for the USB core, but there are the usual "hot spots" of development activity. Included in here are: - Thunderbolt driver updates: - fixes for devices without displayport adapters - lane bonding support and improvements - other minor changes based on device testing - dwc3 gadget driver changes. It seems this driver will never be finished given that the IP core is showing up in zillions of new devices and each implementation decides to do something different with it... - uvc gadget driver updates as more devices start to use and rely on this hardware as well - usb_maxpacket() api changes to remove an unneeded and unused parameter. - usb-serial driver device id updates and small cleanups - typec cleanups and fixes based on device testing - device tree updates for usb properties - lots of other small fixes and driver updates.

extcon: Fix extcon_get_extcon_dev() error handling

2022-05-13T08:03:40Z

The extcon_get_extcon_dev() function returns error pointers on error, NULL when it's a -EPROBE_DEFER defer situation, and ERR_PTR(-ENODEV) when the CONFIG_EXTCON option is disabled. This is very complicated for the callers to handle and a number of them had bugs that would lead to an Oops. In real life, there are two things which prevented crashes. First, error pointers would only be returned if there was bug in the caller where they passed a NULL "extcon_name" and none of them do that. Second, only two out of the eight drivers will build when CONFIG_EXTCON is disabled. The normal way to write this would be to return -EPROBE_DEFER directly when appropriate and return NULL when CONFIG_EXTCON is disabled. Then the error handling is simple and just looks like: dev->edev = extcon_get_extcon_dev(acpi_dev_name(adev)); if (IS_ERR(dev->edev)) return PTR_ERR(dev->edev); For the two drivers which can build with CONFIG_EXTCON disabled, then extcon_get_extcon_dev() will now return NULL which is not treated as an error and the probe will continue successfully. Those two drivers are "typec_fusb302" and "max8997-battery". In the original code, the typec_fusb302 driver had an 800ms hang in tcpm_get_current_limit() but now that function is a no-op. For the max8997-battery driver everything should continue working as is.

usb: typec: tcpci: Don't skip cleanup in .remove() on error

2022-05-05T20:17:43Z

Returning an error value in an i2c remove callback results in an error message being emitted by the i2c core, but otherwise it doesn't make a difference. The device goes away anyhow and the devm cleanups are called. In this case the remove callback even returns early without stopping the tcpm worker thread and various timers. A work scheduled on the work queue, or a firing timer after tcpci_remove() returned probably results in a use-after-free situation because the regmap and driver data were freed. So better make sure that tcpci_unregister_port() is called even if disabling the irq failed. Also emit a more specific error message instead of the i2c core's "remove failed (EIO), will be ignored" and return 0 to suppress the core's warning. This patch is (also) a preparation for making i2c remove callbacks return void.

usb: typec: mux: Add On Semi fsa4480 driver

2022-04-26T11:47:13Z

The ON Semiconductor FSA4480 is a USB Type-C port multimedia switch with support for analog audio headsets. It allows sharing a common USB Type-C port to pass USB2.0 signal, analog audio, sideband use wires and analog microphone signal. Due to lacking upstream audio support for testing, the audio muxing is left untouched, but implementation of muxing the SBU lines is provided as a pair of Type-C mux and switch devices. This provides the necessary support for enabling the DisplayPort altmode on devices with this circuit.
