ALSA: hda - Rename {override,cur}_pin with {user,driver}_pin 



Rename from override_pin and cur_pin with user_pin and driver_pin,
respectively, to be a bit more intuitive.

init_pin_configs::

  Shows the initial pin default config values set by BIOS.

override_pin_configs::

  Shows the pin default config values to override the BIOS setup.

  Writing this (with two numbers, NID and value) appends the new

  value.  The given will be used instead of the initial BIOS value at

  the next reconfiguration time.

cur_pin_configs::

driver_pin_configs::

  Shows the pin default values set by the codec parser explicitly.

  This doesn't show all pin values but only the changed values by

  the parser.  That is, if the parser doesn't change the pin default

  config values by itself, this will contain nothing.

user_pin_configs::

  Shows the pin default config values to override the BIOS setup.

  Writing this (with two numbers, NID and value) appends the new

  value.  The given will be used instead of the initial BIOS value at

  the next reconfiguration time.

reconfig::

  Triggers the codec re-configuration.  When any value is written to

  this file, the driver re-initialize and parses the codec tree
