Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/doc
Pull documentation updates from Jiri Kosina:
"Updates to kernel documentation.
I took this over (hopefully temporarily) from Randy who was not
willing to maintain it any longer. This pile mostly is a relay of
queue that Randy already had in his tree"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/doc:
Documentation: fix broken v4l-utils URL
Documentation: update include path for mpssd
Documentation: correct parameter error for dma_mapping_error
MAINTAINERS: update location of linux-doc tree
Documentation: remove networking/.gitignore

complex devices use the Media Controller (see <xref linkend="media_controller" />)
which can be used for this purpose. But most drivers do not use it,
and while some code exists that uses sysfs to discover related devices
