      ALSA: Add jack reporting API · e76d8cea
      Mark Brown authored
      Currently very few systems provide information about jack status to user
      space, even though many have hardware facilities to do detection. Those
      systems that do use an input device with the existing SW_HEADPHONE_INSERT
      switch type to do so, often independently of ALSA.
      
      This patch introduces a standard method for representing jacks to user
      space into ALSA. It allows drivers to register jacks for a sound card with
      the input subsystem, binding the input device to the card to help user
      space associate the input devices with their sound cards. The created
      input devices are named in the form "card longname jack" where jack is
      provided by the driver when allocating a jack. By default the parent for
      the input device is the sound card but this can be overridden by the
      card driver.
      
      The existing user space API with SW_HEADPHONE_INSERT is preserved.
