Merge tag 'staging-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging/IIO updates from Greg KH:
 "Here is the big Staging and IIO driver patches for 4.16-rc1.

  There is the normal amount of new IIO drivers added, like all
  releases.

  The networking IPX and the ncpfs filesystem are moved into the staging
  tree, as they are on their way out of the kernel due to lack of use
  anymore.

  The visorbus subsystem finall has started moving out of the staging
  tree to the "real" part of the kernel, and the most and fsl-mc
  codebases are almost ready to move out, that will probably happen for
  4.17-rc1 if all goes well.

  Other than that, there is a bunch of license header cleanups in the
  tree, along with the normal amount of coding style churn that we all
  know and love for this codebase. I also got frustrated at the
  Meltdown/Spectre mess and took it out on the dgnc tty driver, deleting
  huge chunks of it that were never even being used.

  Full details of everything is in the shortlog.

  All of these patches have been in linux-next for a while with no
  reported issues"

-# NCP Filesystem configuration
-#
-config NCP_FS
-	tristate "NCP file system support (to mount NetWare volumes)"
-	depends on IPX!=n || INET
-	help
-	  NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
-	  used by Novell NetWare clients to talk to file servers.  It is to
-	  IPX what NFS is to TCP/IP, if that helps.  Saying Y here allows you
-	  to mount NetWare file server volumes and to access them just like
-	  any other Unix directory.  For details, please read the file
-	  <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
-	  the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.
-
-	  You do not have to say Y here if you want your Linux box to act as a
-	  file *server* for Novell NetWare clients.
-
-	  General information about how to connect Linux, Windows machines and
-	  Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.
-
-	  To compile this as a module, choose M here: the module will be called
-	  ncpfs.  Say N unless you are connected to a Novell network.
-
-config NCPFS_PACKET_SIGNING
-	bool "Packet signatures"
-	depends on NCP_FS
-	help
-	  NCP allows packets to be signed for stronger security. If you want
-	  security, say Y.  Normal users can leave it off.  To be able to use
-	  packet signing you must use ncpfs > 2.0.12.
-
-config NCPFS_IOCTL_LOCKING
-	bool "Proprietary file locking"
-	depends on NCP_FS
-	help
-	  Allows locking of records on remote volumes.  Say N unless you have
-	  special applications which are able to utilize this locking scheme.
-
-config NCPFS_STRONG
-	bool "Clear remove/delete inhibit when needed"
-	depends on NCP_FS
-	help
-	  Allows manipulation of files flagged as Delete or Rename Inhibit.
-	  To use this feature you must mount volumes with the ncpmount
-	  parameter "-s" (ncpfs-2.0.12 and newer).  Say Y unless you are not
-	  mounting volumes with -f 444.
-
-config NCPFS_NFS_NS
-	bool "Use NFS namespace if available"
-	depends on NCP_FS
-	help
-	  Allows you to utilize NFS namespace on NetWare servers.  It brings
-	  you case sensitive filenames.  Say Y.  You can disable it at
-	  mount-time with the `-N nfs' parameter of ncpmount.
-
-config NCPFS_OS2_NS
-	bool "Use LONG (OS/2) namespace if available"
-	depends on NCP_FS
-	help
-	  Allows you to utilize OS2/LONG namespace on NetWare servers.
-	  Filenames in this namespace are limited to 255 characters, they are
-	  case insensitive, and case in names is preserved.  Say Y.  You can
-	  disable it at mount time with the -N os2 parameter of ncpmount.
-
-config NCPFS_SMALLDOS
-	bool "Lowercase DOS filenames"
-	depends on NCP_FS
-	---help---
-	  If you say Y here, every filename on a NetWare server volume using
-	  the OS2/LONG namespace and created under DOS or on a volume using
-	  DOS namespace will be converted to lowercase characters.
-	  Saying N here will give you these filenames in uppercase.
-
-	  This is only a cosmetic option since the OS2/LONG namespace is case
-	  insensitive. The only major reason for this option is backward
-	  compatibility when moving from DOS to OS2/LONG namespace support.
-	  Long filenames (created by Win95) will not be affected.
-
-	  This option does not solve the problem that filenames appear
-	  differently under Linux and under Windows, since Windows does an
-	  additional conversions on the client side. You can achieve similar
-	  effects by saying Y to "Allow using of Native Language Support"
-	  below.
-
-config NCPFS_NLS
-	bool "Use Native Language Support"
-	depends on NCP_FS
-	select NLS
-	help
-	  Allows you to use codepages and I/O charsets for file name
-	  translation between the server file system and input/output. This
-	  may be useful, if you want to access the server with other operating
-	  systems, e.g. Windows 95. See also NLS for more Information.
-
-	  To select codepages and I/O charsets use ncpfs-2.2.0.13 or newer.
-
-config NCPFS_EXTRAS
-	bool "Enable symbolic links and execute flags"
-	depends on NCP_FS
-	help
-	  This enables the use of symbolic links and an execute permission
-	  bit on NCPFS. The file server need not have long name space or NFS
-	  name space loaded for these to work.
-
-	  To use the new attributes, it is recommended to use the flags
-	  '-f 600 -d 755' on the ncpmount command line.
