      ALSA: lx6464es: Fix duplicated SSID entries · 1983126f
      Takashi Iwai authored
      PCI_DEVICE() macro itself defines SSID entries while we override them
      after that.  Replace with a more appropriate macro, PCI_DEVICE_SUB()
      to define all ID values properly.

      ALSA: hda - Move hda_i915.c from sound/pci/hda to sound/hda · 98d8fc6c
      Mengdong Lin authored
      The file is moved to hda core and renamed to hdac_i915.c, so can be used
      by both legacy HDA driver and new Skylake audio driver.
      
      - Add snd_hdac_ prefix to the public APIs.
      - The i915 audio component is moved to core bus and dynamically allocated.
      - A static pointer hdac_acomp is used to help bind/unbind callbacks to get
        this component, because the sound card's private_data is used by the azx
        chip pointer, which is a legacy structure. It could be removed if private
        _data changes to some core structure which can be extended to find the
        bus.
      - snd_hdac_get_display_clk() is added to get the display core clock for
        HSW/BDW.
      - haswell_set_bclk() is moved to hda_intel.c because it needs to write the
        controller registers EM4/EM5, and only legacy HD-A needs it for HSW/BDW.
      - Move definition of HSW/BDW-specific registers EM4/EM5 to hda_register.h
        and rename them to HSW_EM4/HSW_EM5, because other HD-A controllers have
        different layout for the extended mode registers.

      Thierry Reding authored
      Commit a41d1224 ("ALSA: hda - Embed bus into controller object")

      This is caused by azx_bus_init() trying to dereference chip->card, which
      for the Tegra driver doesn't get initialized until sometime later during
      the call to hda_tegra_create().
      
      Fix this by mimicking the behaviour of the Intel driver and defer HDA
      bus initialization until right before the call to snd_device_new().
