    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 sound updates from Takashi Iwai:
    "It was a busy development cycle at this time, as you can see a wide
    range of changes in diffstat. There are no big changes but many
    refactoring and improvements. Here we go some highlights:

    ALSA core:
    - Procfs codes were cleaned up to use seq_file
    - Procfs can be opt out via Kconfig (only for EXPERT)
    - Two types of jack API were unified finally; now both kctl and input
    jack devs are handled via a single function call.

    HD-audio:
    - Continued code restructuring for the future ASoC driver; now HDA
    controller driver is split to a core helper module.
    - Preliminary codes for Skylake audio support in HDA core.
    - Proper i915 gfx power well management for SKL & co
    - Enabled runtime PM as default for Intel HDMI/DP codecs
    - Newer Tegra chip supports
    - More quirks for Dell headsets, Alienware (with CA0132), etc.
    - A couple of DRM ELD helper API functions

    ASoC:
    - Support for loading ASoC topology maps from firmware, intended to
    be used to allow self-describing DSP firmware images to be built
    which can map controls added by the DSP to userspace without the
    kernel needing to know about individual DSP firmwares
    - Lots of refactoring to avoid direct access to snd_soc_codec where
    it's not needed supporting future refactoring
    - Big refactoring, cleanup and enhancement for the Wolfson ADSP
    driver
    - Cleanup series for TI TAS2552 and R-CAR drivers
    - Fixes and improvements on RT56xx codecs
    - Support for TI TAS571x power amplifiers
    - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs
    - Support for x86 systems with RT5650 and Qualcomm Storm
    - Support for Mediatek AFE (Audio Front End) unit
    - Other various small fixes to ASoC codec drivers

    Firewire:
    - Enhanced to allow non-blocking streams to use timestamp
    synchronization
    - Improve support for DM1500 and BeBoBv3

    Misc:
    - Cleanup of old pci API functions over all PCI sound drivers
    - Fix long-standing regression of the old powermac i2c setup"

  • 056622053   ALSA: seq: Define driver object in each driver ... Browse Code »

    This patch moves the driver object initialization and allocation to
    each driver's module init/exit code like other normal drivers. The
    snd_seq_driver struct is now published in seq_device.h, and each
    driver is responsible to define it with proper driver attributes
    (name, probe and remove) with snd_seq_driver specific attributes as id
    and argsize fields. The helper functions snd_seq_driver_register(),
    snd_seq_driver_unregister() and module_snd_seq_driver() are used for
    simplifying codes.

    Pull driver core update from Greg KH:
    "Here's the set of driver core patches for 3.19-rc1.

    They are dominated by the removal of the .owner field in platform
    drivers. They touch a lot of files, but they are "simple" changes,
    just removing a line in a structure.

    Other than that, a few minor driver core and debugfs changes. There
    are some ath9k patches coming in through this tree that have been
    acked by the wireless maintainers as they relied on the debugfs
    changes.

    Everything has been in linux-next for a while"

    Replace the lengthy #if defined(XXX) || defined(XXX_MODULE) with the
    new IS_ENABLED() macro.

    The patch still doesn't cover all ifdefs. For example, the dependency
    on CONFIG_GAMEPORT is still open-coded because this also has an extra
    dependency on MODULE. Similarly, an open-coded ifdef in pcm_oss.c and
    some sequencer-related stuff are left untouched.
