Merge tag 'media/v4.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- Lots of improvements at the DVB API DocBook documentation. Now, the
frontend and the network APIs are fully in sync with the Kernel and
looks more like the rest of the media documentation;
- New frontend driver: cx24120
- New driver for a PCI device: cobalt. This driver is actually not
sold in the market, but it is a good example of a multi-HDMI input
device;
- The dt3155 driver were promoted from staging;
- The mantis driver got remote controller support;
- New V4L2 driver for ST bdisp SoC chipsets;
- Make sparse and smatch happier: several bugs were solved by fixing
the issues reported by those static code analyzers.
- Lots of new device additions, new features, improvements and cleanups
at the existing drivers.
