Pull Documentation updates from Jon Corbet:
 "A bit busier this time around.

  The most interesting thing (IMO) this time around is some beginning
  infrastructural work to allow documents to be written using
  restructured text.  Maybe someday, in a galaxy far far away, we'll be
  able to eliminate the DocBook dependency and have a much better
  integrated set of kernel docs.  Someday.

  Beyond that, there's a new document on security hardening from Kees,
  the movement of some sample code over to samples/, a number of
  improvements to the serial docs from Geert, and the usual collection
  of corrections, typo fixes, etc"

[media] samples: v4l: from Documentation to samples directory

2016-05-09T21:34:37+00:00

With the new autoksyms support, we can run into a situation where
the v4l pci skeleton module is the only one using some exported
symbols that get dropped because they are never referenced by
the kernel otherwise, causing a build problem:

ERROR: "vb2_dma_contig_memops" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!
ERROR: "vb2_dma_contig_init_ctx_attrs" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!
ERROR: "v4l2_match_dv_timings" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!
ERROR: "v4l2_find_dv_timings_cap" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!
ERROR: "v4l2_valid_dv_timings" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!
ERROR: "v4l2_enum_dv_timings_cap" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!
ERROR: "vb2_dma_contig_cleanup_ctx" [Documentation/video4linux/v4l2-pci-skeleton.ko] undefined!

Specifically, we do look in the samples directory for users of
symbols, but not the Documentation directory.

This solves the build problem by moving the connector sample into
the same directory as the other samples.

[media] em28xx: add support for Hauppauge WinTV-dualHD DVB tuner

2016-05-09T17:25:39+00:00

Hauppauge WinTV-dualHD is a USB 2.0 dual DVB-T/T2/C tuner with
following components:

USB bridge: Empia EM28274 (chip id is the same as EM28174)
Demodulator: 2x Silicon Labs Si2168-B40
Tuner: 2x Silicon Labs Si2157-A30

This patch adds support only for the first tuner.

The demodulator needs firmware, available for example here:
http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.11/

The demodulators sit on the same I2C bus and their addresses
are 0x64 and 0x67. The tuners are behind the demodulators and
their addresses are 0x60 and 0x63.

samples: v4l: from Documentation to samples directory

2016-04-28T13:47:59+00:00

A small bug with the new autoksyms support showed that there are
two kernel modules in the Documentation directory that qualify
as samples, while all other samples are in the samples/ directory.

This patch was originally meant as a workaround for that bug, but
it has now been solved in a different way. However, I still think
it makes sense as a cleanup to consolidate all sample code in
one place.
