Merge tag 'usb-7.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usbHEADmaster
Pull USB and Thunderbolt fixes from Greg KH: "Here is a set of USB fixes and new device ids for 7.1-rc6. Nothing major in here, just lots of tiny fixes for reported issues found by users and some older patches found by some scanning tools. Included in here are: - typec fixes found by fuzzers that have decided to finally look at that device interaction path (i.e. before a driver is bound to a device) - typec fixes for issues found by users - thunderbolt driver fixes for reported problems - cdns3 driver fixes - dwc3 driver fixes - new device quirks added - usb serial driver fixes for broken devices - other small driver fixes All of these have been in linux-next for over a week with no reported issues" * tag 'usb-7.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (54 commits) USB: serial: cypress_m8: validate interrupt packet headers USB: serial: safe_serial: fix memory corruption with small endpoint USB: serial: omninet: fix memory corruption with small endpoint USB: serial: mxuport: fix memory corruption with small endpoint USB: serial: cypress_m8: fix memory corruption with small endpoint USB: cdc-acm: Fix bit overlap and move quirk definitions to header usb: dwc2: Fix use after free in debug code usb: chipidea: core: convert ci_role_switch to local variable usb: gadget: f_fs: serialize DMABUF cancel against request completion usb: gadget: f_fs: copy only received bytes on short ep0 read usb: gadget: dummy_hcd: Reject hub port requests for non-existent ports dt-bindings: usb: Fix EIC7700 USB reset's issue usbip: vudc: Fix use after free bug in vudc_remove due to race condition dt-bindings: usb: ti,omap4-musb: Drop duplicate 'usb-phy' property constraints usb: storage: Add quirks for PNY Elite Portable SSD USB: quirks: add NO_LPM for Lenovo ThinkPad USB-C Dock Gen2 hub controllers usb: usbtmc: reject interrupt endpoints with small wMaxPacketSize usb: usbtmc: check URB actual_length for interrupt-IN notifications xhci: tegra: Fix ghost USB device on dual-role port unplug usb: gadget: uvc: hold opts->lock across XU walks in uvc_function_bind ...
