Merge tag 'staging-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging tree update from Greg KH:
 "Here's the large staging tree merge for 3.11-rc1

  Huge thing here is the Lustre client code.  Unfortunatly, due to it
  not building properly on a wide variety of different architectures
  (this was production code???), it is currently disabled from the build
  so as to not annoy people.

  Other than Lustre, there are loads of comedi patches, working to clean
  up that subsystem, iio updates and new drivers, and a load of cleanups
  from the OPW applicants in their quest to get a summer internship.

  All of these have been in the linux-next releases for a while (hence
  the Lustre code being disabled)"

Fixed up trivial conflict in drivers/staging/serqt_usb2/serqt_usb2.c due
to independent renamings in the staging driver cleanup and the USB
tree..

+	 *	Interval field of the Device Configuration register
+	 *	(DCFG.PerFrInt) has been reached in the current microframe.
+	 * @isooutdrop: Isochronous OUT Packet Dropped Interrupt (ISOOutDrop)
+	 *	The core sets this bit when it fails to write an isochronous OUT
+	 *	packet into the RxFIFO because the RxFIFO doesn't have
+	 *	enough space to accommodate a maximum packet size packet
+	 *	for the isochronous OUT endpoint.
+	 * @enumdone: Enumeration Done (EnumDone)
+	 *	The core sets this bit to indicate that speed enumeration is
+	 *	complete. The application must read the Device Status (DSTS)
+	 *	register to obtain the enumerated speed.
+	 * @usbrst: USB Reset (USBRst)
+	 *	The core sets this bit to indicate that a reset is detected on
+	 *	the USB.
+	 * @usbsusp: USB Suspend (USBSusp)
+	 *	The core sets this bit to indicate that a suspend was detected

+	 *	is no activity on the phy_line_state_i signal for an extended
+	 *	period of time.
+	 * @erlysusp: Early Suspend (ErlySusp)
+	 *	The core sets this bit to indicate that an Idle state has been

+	 * @ulpickint: ULPI Carkit Interrupt (ULPICKINT)

+	 *	effect in the core. This bit can be cleared by writing the Clear
+	 *	Global OUT NAK bit in the Device Control register
+	 *	(DCTL.CGOUTNak).
+	 * @ginnakeff: Global IN Non-Periodic NAK Effective (GINNakEff)
+	 *	Indicates that the Set Global Non-Periodic IN NAK bit in the
+	 *	Device Control register (DCTL.SGNPInNak), set by the
+	 *	application, has taken effect in the core. That is, the core has
+	 *	sampled the Global IN NAK bit set by the application. This bit
+	 *	can be cleared by clearing the Clear Global Non-Periodic IN
+	 *	NAK bit in the Device Control register (DCTL.CGNPInNak).
+	 *	This interrupt does not necessarily mean that a NAK handshake
+	 *	is sent out on the USB. The STALL bit takes precedence over
+	 *	the NAK bit.
+	 * @nptxfemp: Non-Periodic TxFIFO Empty (NPTxFEmp)
+	 *	This interrupt is asserted when the Non-Periodic TxFIFO is
+	 *	either half or completely empty, and there is space for at least
+	 *	one entry to be written to the Non-Periodic Transmit Request
+	 *	Queue. The half or completely empty status is determined by
+	 *	the Non-Periodic TxFIFO Empty Level bit in the Core AHB
+	 *	Configuration register (GAHBCFG.NPTxFEmpLvl).
+	 * @rxflvl: RxFIFO Non-Empty (RxFLvl)
+	 *	Indicates that there is at least one packet pending to be read
+	 *	from the RxFIFO.
+	 * @sof: Start of (micro)Frame (Sof)
+	 *	In Host mode, the core sets this bit to indicate that an SOF
+	 *	(FS), micro-SOF (HS), or Keep-Alive (LS) is transmitted on the
+	 *	USB. The application must write a 1 to this bit to clear the
+	 *	interrupt.
+	 *	In Device mode, in the core sets this bit to indicate that an
+	 *	SOF token has been received on the USB. The application can read
+	 *	the Device Status register to get the current (micro)frame
+	 *	number. This interrupt is seen only when the core is operating
+	 *	at either HS or FS.
+	 * @otgint: OTG Interrupt (OTGInt)
+	 *	The core sets this bit to indicate an OTG protocol event. The
+	 *	application must read the OTG Interrupt Status (GOTGINT)
+	 *	register to determine the exact event that caused this
+	 *	interrupt. The application must clear the appropriate status bit
+	 *	in the GOTGINT register to clear this bit.
+	 * @modemis: Mode Mismatch Interrupt (ModeMis)
+	 *	The core sets this bit when the application is trying to access:
+	 *	* A Host mode register, when the core is operating in Device
+	 *	mode
+	 *	* A Device mode register, when the core is operating in Host
+	 *	mode
+	 *	The register access is completed on the AHB with an OKAY
