Merge tag 'usb-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

2024-11-29T19:19:31Z

Pull USB / Thunderbolt updates from Greg KH: "Here is the big set of USB and Thunderbolt changes for 6.13-rc1. Overall, a pretty slow development cycle, the majority of the work going into the debugfs interface for the thunderbolt (i.e. USB4) code, to help with debugging the myrad ways that hardware vendors get their interfaces messed up. Other than that, here's the highlights: - thunderbolt changes and additions to debugfs interfaces - lots of device tree updates for new and old hardware - UVC configfs gadget updates and new apis for features - xhci driver updates and fixes - dwc3 driver updates and fixes - typec driver updates and fixes - lots of other small updates and fixes, full details in the shortlog All of these have been in linux-next for a while with no reported problems" * tag 'usb-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (148 commits) usb: typec: tcpm: Add support for sink-bc12-completion-time-ms DT property dt-bindings: usb: maxim,max33359: add usage of sink bc12 time property dt-bindings: connector: Add time property for Sink BC12 detection completion usb: dwc3: gadget: Remove dwc3_request->needs_extra_trb usb: dwc3: gadget: Cleanup SG handling usb: dwc3: gadget: Fix looping of queued SG entries usb: dwc3: gadget: Fix checking for number of TRBs left usb: dwc3: ep0: Don't clear ep0 DWC3_EP_TRANSFER_STARTED Revert "usb: gadget: composite: fix OS descriptors w_value logic" usb: ehci-spear: fix call balance of sehci clk handling routines USB: make to_usb_device_driver() use container_of_const() USB: make to_usb_driver() use container_of_const() USB: properly lock dynamic id list when showing an id USB: make single lock for all usb dynamic id lists drivers/usb/storage: refactor min with min_t drivers/usb/serial: refactor min with min_t drivers/usb/musb: refactor min/max with min_t/max_t drivers/usb/mon: refactor min with min_t drivers/usb/misc: refactor min with min_t drivers/usb/host: refactor min/max with min_t/max_t ...

drivers/usb/serial: refactor min with min_t

USB: serial: io_edgeport: fix use after free in debug printk

2024-10-31T13:18:51Z

The "dev_dbg(&urb->dev->dev, ..." which happens after usb_free_urb(urb) is a use after free of the "urb" pointer. Store the "dev" pointer at the start of the function to avoid this issue.

USB: serial: drop driver owner initialization

Core in usb_serial_register_drivers() already sets the .owner, so driver does not need to. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Johan Hovold

USB: serial: return errors from break handling

2023-06-07T15:00:23Z

Start propagating errors to user space when setting the break state fails. This will be used by follow-on changes to also report when a driver or device does not support break control. Tested-by: Corey Minyard Signed-off-by: Johan Hovold

USB: serial: io_edgeport: drop buffer-callback sanity checks

2021-05-21T13:46:08Z

The driver write_room and chars_in_buffer callbacks used to incorrectly return a negative errno in case they were called while or after the port had been closed. The return value was later changed to zero by commit d76f2f4462bb ("io_edgeport: Fix various bogus returns to the tty layer") but the bogus sanity checks were left in place as were the outdated function-header comments. These callbacks will never be called for an uninitialised port so drop the unnecessary sanity checks and the outdated comments. Reviewed-by: Greg Kroah-Hartman Signed-off-by: Johan Hovold
