Merge tag 'usb-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB patches from Greg Kroah-Hartman: "Here's the big USB pull request for 3.10-rc1. Lots of USB patches here, the majority being USB gadget changes and USB-serial driver cleanups, the rest being ARM build fixes / cleanups, and individual driver updates. We also finally got some chipidea fixes, which have been delayed for a number of kernel releases, as the maintainer has now reappeared. All of these have been in linux-next for a while" * tag 'usb-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (568 commits) USB: ehci-msm: USB_MSM_OTG needs USB_PHY USB: OHCI: avoid conflicting platform drivers USB: OMAP: ISP1301 needs USB_PHY USB: lpc32xx: ISP1301 needs USB_PHY USB: ftdi_sio: enable two UART ports on ST Microconnect Lite usb: phy: tegra: don't call into tegra-ehci directly usb: phy: phy core cannot yet be a module USB: Fix initconst in ehci driver usb-storage: CY7C68300A chips do not support Cypress ATACB USB: serial: option: Added support Olivetti Olicard 145 USB: ftdi_sio: correct ST Micro Connect Lite PIDs ARM: mxs_defconfig: add CONFIG_USB_PHY ARM: imx_v6_v7_defconfig: add CONFIG_USB_PHY usb: phy: remove exported function from __init section usb: gadget: zero: put function instances on unbind usb: gadget: f_sourcesink.c: correct a copy-paste misnomer usb: gadget: cdc2: fix error return code in cdc_do_config() usb: gadget: multi: fix error return code in rndis_do_config() usb: gadget: f_obex: fix error return code in obex_bind() USB: storage: convert to use module_usb_driver() ...
