Pull media fixes from Mauro Carvalho Chehab: "For some last time fixes: - a regression detected on Kernel 3.16 related to VBI Teletext application breakage on drivers using videobuf2 (see https://bugzilla.kernel.org/show_bug.cgi?id=84401). The bug was noticed on saa7134 (migrated to VB2 on 3.16), but also affects em28xx (migrated on 3.9 to VB2); - two additional sanity checks at videobuf2; - two fixups to restore proper VBI support at the em28xx driver; - two Kernel oops fixups (at cx24123 and cx2341x drivers); - a bug at adv7604 where an if was doing just the opposite as it would be expected; - some documentation fixups to match the behavior defined at the Kernel" * tag 'media/v3.17-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: [media] em28xx-v4l: get rid of field "users" in struct em28xx_v4l2" [media] em28xx: fix VBI handling logic [media] DocBook media: improve the poll() documentation [media] DocBook media: fix the poll() 'no QBUF' documentation [media] vb2: fix VBI/poll regression [media] cx2341x: fix kernel oops [media] cx24123: fix kernel oops due to missing parent pointer [media] adv7604: fix inverted condition [media] media/radio: fix radio-miropcm20.c build with io.h header file [media] vb2: fix plane index sanity check in vb2_plane_cookie() [media] DocBook media: update version number and V4L2 changes [media] DocBook media: fix fieldname in struct v4l2_subdev_selection [media] vb2: fix vb2 state check when start_streaming fails [media] videobuf2-core.h: fix comment [media] videobuf2-core: add comments before the WARN_ON [media] videobuf2-dma-sg: fix for wrong GFP mask to sg_alloc_table_from_pages
