Merge tag 'staging-3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging tree patches from Greg Kroah-Hartman:
 "Here's the big staging tree merge for the 3.6-rc1 merge window.

  There are some patches in here outside of drivers/staging/, notibly
  the iio code (which is still stradeling the staging / not staging
  boundry), the pstore code, and the tracing code.  All of these have
  gotten acks from the various subsystem maintainers to be included in
  this tree.  The pstore and tracing patches are related, and are coming
  here as they replace one of the android staging drivers.

  Otherwise, the normal staging mess.  Lots of cleanups and a few new
  drivers (some iio drivers, and the large csr wireless driver
  abomination.)

  Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"

Fixed up trivial conflicts in drivers/staging/comedi/drivers/s626.h and
drivers/staging/gdm72xx/netlink_k.c

+ * Porting Notes:
+ * There are two ways to support the suspend/resume system events in a driver.
+ * In some operating systems these events are delivered to the OS driver
+ * directly from the system. In this case, the OS driver needs to pass these
+ * events to the API described in the CSR SDIO Abstration API document.
+ * In Linux, and other embedded operating systems, the suspend/resume events
+ * come from the SDIO driver. In this case, simply get these events in the
+ * SDIO glue layer and notify the OS layer.
+ *
+ * In either case, typically, the events are processed by the SME.
+ * Use the unifi_sys_suspend_ind() and unifi_sys_resume_ind() to pass
+ * the events to the SME.
