sound fixes for 4.6-rc1

The previous pull request introduced a few WARN_ON() for Intel
HD-audio HDMI.  Indeed it caught bugs, and now users get annoyed.
So this request came up: a collection of small fixes to paper over
the inconsistencies on (mostly) old Intel chipsets.

In addition, a trivial USB-audio quirk is included, too.

sound updates for 4.6-rc1

After a heavy storm by syzkaller in 4.5 cycle, we have relatively few
changes in the core at this time while a lot of changes are found in
the driver side, unsurprisingly.  Below are some highlights:

ALSA core:
- A few more hardening in ALSA timer codes
- An extension of sequencer API for advertising the card / pid
- Small fixes in compress-offload and jack layers

HD-audio:
- Dynamic PCM assignment in HDMI/DP codec; preparation for upcoming
  DP-MST support
- Lots of code refactoring for sharing with ASoC SKL driver
- Regression fixes for Intel HDMI/DP
- Fixups for CX20724 codec, Lenovo AiO

USB-audio:
- Add quirk_alias option to make quirk debugging easier
- Fixes for possible Oops by malformed firmware

Firewire:
- Add support for FW-1804 in tascam driver
- Improvements / changes in card registration, multi stream handling,
  etc for DICE
- Lots of code refactoring

ASoC:
- Enhancements of still ongoing topology API
- Lots of commits for Intel Skylake support including HDMI support
- A few Intel Atom driver updates for recent devices
- Lots of improvements to the Renesas drivers
- Capture support for Qualcomm drivers
- Support for TI DaVinci DRA7xxx devices
- New machine drivers for Freescale systems with Cirrus CODECs,
  Mediatek systems with RT5650 CODECs
- New CPU drivers for Allwinner S/PDIF controllers
- New CODEC drivers for Maxim MAX9867 and MAX98926 and Realtek RT5514

- two-stage wm updates for ilk-style platforms (Matt)
- more wm work and fixes from Maarten&Ville
- more work on rotated framebuffers to prep for rotated nv12 (Ville)
- more dc fixes (Imre)
- various execlist patches from Tvrtko
- various clock cleanups for gmch from Ville
- extract intel_dpll_mgr.c and refactor shared dpll code (Ander)

Linux 4.5

sound fixes for 4.5

It's always an ambivalent feeling to send a large pull request at the
late stage like this, especially when most of patches came from me.
In anyway, this is a collection of lots of small fixes that slipped
from the previous pull request.

All fixes are about ASoC, and the majority of changes are corrections
of the wrong access types in ALSA ctl enum items.  They are mostly
harmless on 32bit architectures, but actually buggy on 64bit.  So we
addressed all these now in a shot.  The rest are various small ASoC
driver fixes.

Among them, only two changes have been done to ASoC core, and both of
them are trivial.  The rest are all device-specific.  So overall, they
should be safe to apply.

Linux 4.5-rc7

sound fixes for 4.5-rc7

It's our tradition to get a high volume of fixes late at rc7: this
time, X32 ABI breakage was found and this resulted in a high number
LOCs.  The necessary changes to ALSA core codes were fairly
straightforward, and more importantly, they are specific to X32, thus
should be safe to apply.

Other than that, rather a collection of small fixes:
- Removal of the code that blocks too long at closing the OSS
  sequencer client (which was spotted by syzkaller, unsurprisingly)
- Fixes races at HD-audio HDMI i915 audio binding
- a few HDSP/HDPM zero-division fixes
- Quirks for HD-audio and USB-audio as usual

- fbc by default on hsw&bdw, thanks to great work by Paulo!
- psr by default hsw,bdw,vlv&chv, thanks to great work by Rodrigo!
- fixes to hw state readout vs. rpm issues (Imre)
- dc3 fixes&improvements (Mika), this and above already cherr-pick to -fixes
- first part of locking fixes from Tvrtko
- proper atomic code for load detect (Maarten)
- more rpm fixes from Ville
- more atomic work from Maarten

Linux 4.5-rc6

sound fixes for 4.5-rc6

Things got calmed down for rc6, as it seems, and we have only a few
HD-audio fixes at this time: a fix for Skylake codec probe errors,
a fix for missing interrupt handling, and a few Dell and HP quirks.

Linux 4.5-rc5

sound fixes for 4.5-rc5

this update contains again a few more fixes for ALSA core stuff
although it's no longer high flux: two race fixes in sequencer and one
PCM race fix for non-atomic PCM ops.  In addition, HD-audio gained a
similar fix for race at reloading the driver.

- lots and lots of fbc work from Paulo
- max pixel clock checks from Mika Kahola
- prep work for nv12 offset handling from Ville
- piles of small fixes and refactorings all around

Linux 4.5-rc4

another sound fix for 4.5-rc4

This contains the last-minute fix for the double-free of usb-audio
MIDI device at probe failure.

sound fixes for 4.5-rc4

In this rc, we've got more volume than previous rc, unsurprisingly;
the majority of updates in ASoC are about Intel drivers, and another
major changes are the continued plumbing of ALSA timer bugs revealed
by syzkaller fuzzer.  Hopefully both settle down now.

Other than that, HD-audio received a couple of code fixes as well as
the usual quirks, and various small fixes are found for FireWire
devices, ASoC codecs and drivers.

Linux 4.5-rc3

sound fixes for 4.5-rc3

This was a busy week and I had to prepare a pile of duct tapes for
the bugs reported by syzkaller fuzzer in wide range of ALSA core
APIs: timer, rawmidi, sequencer, and PCM OSS emulation.  Let's see
how many other holes we need to plug.

Besides that, a few usual boring stuff, HD- and USB-audio quirks,
have been added.

Linux 4.5-rc2

sound fixes for 4.5-rc2

There are a few fixes in ALSA core for bugs that have been spotted by
fuzzer.  Also a temporary workaround for PowerPC (and possibly other)
builds with incompatible ioctls was applied to compress API.

Other than that, a few trivial fixes and quirks for FireWire BeBoB,
USB-audio and HD-audio are found, too.
