Merge branch 'usb-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb-2.6
* 'usb-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb-2.6: (144 commits) USB: add support for Dream Cheeky DL100B Webmail Notifier (1d34:0004) USB: serial: ftdi_sio: add support for TIOCSERGETLSR USB: ehci-mxc: Setup portsc register prior to accessing OTG viewport USB: atmel_usba_udc: fix freeing irq in usba_udc_remove() usb: ehci-omap: fix tll channel enable mask usb: ohci-omap3: fix trivial typo USB: gadget: ci13xxx: don't assume that PAGE_SIZE is 4096 USB: gadget: ci13xxx: fix complete() callback for no_interrupt rq's USB: gadget: update ci13xxx to work with g_ether USB: gadgets: ci13xxx: fix probing of compiled-in gadget drivers Revert "USB: musb: pm: don't rely fully on clock support" Revert "USB: musb: blackfin: pm: make it work" USB: uas: Use GFP_NOIO instead of GFP_KERNEL in I/O submission path USB: uas: Ensure we only bind to a UAS interface USB: uas: Rename sense pipe and sense urb to status pipe and status urb USB: uas: Use kzalloc instead of kmalloc USB: uas: Fix up the Sense IU usb: musb: core: kill unneeded #include's DA8xx: assign name to MUSB IRQ resource usb: gadget: g_ncm added ... Manually fix up trivial conflicts in USB Kconfig changes in: arch/arm/mach-omap2/Kconfig arch/sh/Kconfig drivers/usb/Kconfig drivers/usb/host/ehci-hcd.c and annoying chip clock data conflicts in: arch/arm/mach-omap2/clock3xxx_data.c arch/arm/mach-omap2/clock44xx_data.c
