Pull sound updates from Takashi Iwai:
"We've had quite busy weeks in this cycle. Looking at ALSA core, the
significant changes are a few fixes wrt timer and sequencer ioctls
that have been revealed by fuzzer recently. Other than that, ASoC
core got a few updates about DAI link handling, but these are rather
straightforward refactoring.
In drivers scene, ASoC received quite lots of new drivers in addition
to bunch of updates for still ongoing Intel Skylake support and
topology API. HD-audio gained a new HDMI/DP hotplug notification via
component. FireWire got a pile of code refactoring/updates with
SCS.1x driver integration.
More highlights are shown below.
[ NOTE: this contains also many commits for DRM. This is due to the
pull of drm stable branch into sound tree, as the base of i915 audio
component work for HD-audio. The highlights below don't contain
these DRM changes, as these are supposed to be pulled via drm tree
in anyway sooner or later. ]
Core:
- Handful fixes to harden ALSA timer and sequencer ioctls against
races reported by syzkaller fuzzer
- Irq description string can be unique to each card; only for
HD-audio for now
ASoC:
- Conversion of the array of DAI links to a list for supporting
dynamically adding and removing DAI links
- Topology API enhancements to make everything more component based
and being able to specify PCM links via topology
- Some more fixes for the topology code, though it is still not final
and ready for enabling in production; we really need to get to the
point where that can be done
- A pile of changes for Intel SkyLake drivers which hopefully deliver
some useful initial functionality for systems with this chipset,
though there is more work still to come
- Lots of new features and cleanups for the Renesas drivers
- ANC support for WM5110
- New drivers: Imagination Technologies IPs, Atmel class D speaker,
Cirrus CS47L24 and WM1831, Dialog DA7128, Realtek RT5659 and
RT56156, Rockchip RK3036, TI PC3168A, and AMD ACP
- Rename PCM1792a driver to be generic pcm179x
HD-Audio:
- Use audio component for i915 HDMI/DP hotplug handling
- On-demand binding with i915 driver
- bdl_pos_adj parameter adjustment for Baytrail controllers
- Enable power_save_node for CX20722; this shouldn't lead to
regression, hopefully
- Kabylake HDMI/DP codec support
- Quirks for Lenovo E50-80, Dell Latitude E-series, and other Dell
machines
- A few code refactoring
FireWire:
- Lots of code cleanup and refactoring
- Integrate the support of SCS.1x devices into snd-oxfw driver;
snd-scs1x driver is obsoleted
USB-audio:
- Fix possible NULL dereference at disconnection
- A regression fix for Native Instruments devices
Misc:
- A few code cleanups of fm801 driver"

Pull second batch of media updates from Mauro Carvalho Chehab:
"This is the second part of the media patches. It contains the media
controller next generation patches, with is the result of one year of
discussions and development. It also contains patches to enable media
controller support at the DVB subsystem.
The goal is to improve the media controller to allow proper support
for other types of Video4Linux devices (radio and TV ones) and to
extend the media controller functionality to allow it to be used by
other subsystems like DVB, ALSA and IIO.
In order to use the new functionality, a new ioctl is needed
(MEDIA_IOC_G_TOPOLOGY). As we're still discussing how to pack the
struct fields of this ioctl in order to avoid compat32 issues, I
decided to add a patch at the end of this series commenting out the
new ioctl, in order to postpone the addition of the new ioctl to the
next Kernel version (4.6).
With that, no userspace visible changes should happen at the media
controller API, as the existing ioctls are untouched. Yet, it helps
DVB, ALSA and IIO developers to develop and test the patches adding
media controller support there, as the core will contain all required
internal changes to allow adding support for devices that belong to
those subsystems"

Pull MTD updates from Brian Norris:
"Generic MTD:
- populate the MTD device 'of_node' field (and get a proper 'of_node'
symlink in sysfs)
This yielded some new helper functions, and changes across a
variety of drivers
- partitioning cleanups, to prepare for better device-tree based
partitioning in the future
Eliminate a lot of boilerplate for drivers that want to use
OF-based partition parsing
The DT bindings for this didn't settle yet, so most non-cleanup
portions are deferred for a future release
NAND:
- embed a struct mtd_info inside struct nand_chip
This is really long overdue; too many drivers have to do the same
silly boilerplate to allocate and link up two "independent"
structs, when in fact, everyone is assuming there is an exact 1:1
relationship between a NAND chips struct and its underlying MTD.
This aids improved helpers and should make certain abstractions
easier in the future.
Also causes a lot of churn, helped along by some automated code
transformations
- add more core support for detecting (and "correcting") bitflips in
erased pages; requires opt-in by drivers, but at least we kill a
few bad implementations and hopefully stave off future ones
- pxa3xx_nand: cleanups, a few fixes, and PM improvements
- new JZ4780 NAND driver
SPI NOR:
- provide default erase function, for controllers that just want to
send the SECTOR_ERASE command directly
- fix some module auto-loading issues with device tree
("jedec,spi-nor")
- error handling fixes
- new Mediatek QSPI flash driver
Other:
- cfi: force valid geometry Kconfig (finally!)
This one used to trip up randconfigs occasionally, since bots
aren't deterred by big scary "advanced configuration" menus
More? Probably. See the commit logs"

There are a few discussions left with regards to this ioctl:
1) the name of the new structs will contain _v2_ on it?
2) what's the best alternative to avoid compat32 issues?
Due to that, let's postpone the addition of this new ioctl to
the next Kernel version, to give people more time to discuss it.

As MEDIA_IOC_G_TOPOLOGY shares the data types already declared
for entities, pads and links, we should move those to a separate
part of the document, and use cross-references where needed.
So, move the following tables to a separate section at the

Cleanup the media controller entities description:
- remove MEDIA_ENT_T_DEVNODE and MEDIA_ENT_T_V4L2_SUBDEV entity
types, as they don't mean anything;
- add MEDIA_ENT_T_UNKNOWN with a proper description;
- remove ALSA and FB entity types. Those should not be used, as
the types are deprecated. We'll soon be adidng ALSA, but with
a different entity namespace;
- improve the description of some entities.

During the Seoul media workshop we decided to relax the VIDIOC_CREATE_BUFS
specification so it would no longer require drivers to validate the format
field since almost no driver did that anyway.
Instead drivers use the buffer size(s) based on the format type and the
corresponding format fields and will ignore any other fields. If the size
cannot be used an error is returned, otherwise the size is used as-is.
