Merge tag 'usb-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB updates from Greg KH: "Here's the big set of USB and PHY patches for 3.19-rc1. The normal churn in the USB gadget area is in here, as well as xhci and other individual USB driver updates. The PHY tree is also in here, as there were dependancies on the USB tree. All of these have been in linux-next" * tag 'usb-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (351 commits) arm: omap3: twl: remove usb phy init data usbip: fix error handling in stub_probe() usb: gadget: udc: missing curly braces USB: mos7720: delete some unneeded code wusb: replace memset by memzero_explicit usbip: remove unneeded structure usb: xhci: fix comment for PORT_DEV_REMOVE xhci: don't use the same variable for stopped and halted rings current TD xhci: clear extra bits from slot context when setting max exit latency xhci: cleanup finish_td function USB: adutux: NULL dereferences on disconnect usb: chipidea: fix platform_no_drv_owner.cocci warnings usb: chipidea: Fixed a few typos in comments Documentation: bindings: add doc for the USB2 ChipIdea USB driver usb: chipidea: add a usb2 driver for ci13xxx usb: chipidea: fix phy handling usb: chipidea: remove duplicate dev_set_drvdata for host_start usb: chipidea: parameter 'mode' isn't needed for hw_device_reset usb: chipidea: add controller reset API usb: chipidea: remove flag CI_HDRC_REQUIRE_TRANSCEIVER ...
