Merge tag 'usb-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY updates from Greg KH: "Here is the big set of USB and PHY driver updates for 4.15-rc1. There is the usual amount of gadget and xhci driver updates, along with phy and chipidea enhancements. There's also a lot of SPDX tags and license boilerplate cleanups as well, which provide some churn in the diffstat. Other major thing is the typec code that moved out of staging and into the "real" part of the drivers/usb/ tree, which was nice to see happen. All of these have been in linux-next with no reported issues for a while" * tag 'usb-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (263 commits) usb: gadget: f_fs: Fix use-after-free in ffs_free_inst USB: usbfs: compute urb->actual_length for isochronous usb: core: message: remember to reset 'ret' to 0 when necessary USB: typec: Remove remaining redundant license text USB: typec: add SPDX identifiers to some files USB: renesas_usbhs: rcar?.h: add SPDX tags USB: chipidea: ci_hdrc_tegra.c: add SPDX line USB: host: xhci-debugfs: add SPDX lines USB: add SPDX identifiers to all remaining Makefiles usb: host: isp1362-hcd: remove a couple of redundant assignments USB: adutux: remove redundant variable minor usb: core: add a new usb_get_ptm_status() helper usb: core: add a 'type' parameter to usb_get_status() usb: core: introduce a new usb_get_std_status() helper usb: core: rename usb_get_status() 'type' argument to 'recip' usb: core: add Status Type definitions USB: gadget: Remove redundant license text USB: gadget: function: Remove redundant license text USB: gadget: udc: Remove redundant license text USB: gadget: legacy: Remove redundant license text ...
