sound fixes for 5.0-rc2

A collection of small fixes for USB-audio, HD-audio and cs46xx.
The USB-audio fixes are for out-of-bound accesses and a regression
in the recent cleanup, while HD-audio fixes are usual device-
specific quirks.

  tc358867 using a DP connector.

Linux 5.0-rc1

drm i915 gvt, amdgpu, core fixes

sound fixes for 4.21-rc1 (or whatever the next)

Among a few HD-audio fixes, the only significant one is the
regression fix on some machines like Dell XPS due to the default
binding changes.  We ended up reverting the whole since the fix for
ASoC HD-audio driver won't be available immediately.

Fixes for v4.21:
- Fix null pointer dereference on null state pointer.
- Fix leaking damage clip when destroying plane state.

Make some drm headers self-contained with includes and forward declarations

final drm-fixes for 4.20

array_index_nospec patch, cc: stable

Fix spectre v1 vuln in drm_ioctl

sound updates for 4.21

There are no intensive changes in both ALSA and ASoC core parts while
rather most of changes are a bunch of driver fixes and updates.
A large diff pattern appears in ASoC TI part which now merges both
OMAP and DaVinci stuff, but the rest spreads allover the places.

Note that this pull request includes also some updates for LED trigger
and platform drivers for mute LEDs, appearing in the diffstat as well.

Some highlights:

ASoC:
- Preparatory work for merging the audio-graph and audio-graph-scu
  cards
- A merge of TI OMAP and DaVinci directories, as both product lines
  get merged together.  Also including a few architecture changes as
  well.
- Major cleanups of the Maxim MAX9867 driver
- Small fixes for tablets & co with Intel BYT/CHT chips
- Lots of rsnd updates as usual
- Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
  RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
  controllers

HD-audio:
- Introduce audio-mute LED trigger for replacing the former hackish
  dynamic binding
- Huawei WMI hotkey and mute LED support
- Refactoring of PM code and display power controls
- Headset button support in the generic jack code
- A few updates for Tegra
- Fixups for HP EliteBook and ASUS UX391UA
- Lots of updates for Intel ASoC HD-audio, including the improved DSP
  detection and the fallback binding from ASoC SST to legacy HD-audio
  controller drivers

Others:
- Updates for FireWire TASCAM and Fireface devices, some other fixes
- A few potential Spectre v1 fixes that are all trivial

Linux 4.20-rc7

drm pull request for 4.21-rc1

drm vmwgfx, mediatek, nouveau, amdgpu, rockchip, intel fixes

sound fixes for 4.20-rc7

Only usual suspects here: a few more fixups for Realtek HD-audio on
various PCs, including a regression fix in the previous fix for
Lenovo X1 Carbon, as well as a typo fix in the recent Fireface patch.
