Added code to allow a user - * to only use this driver for enabling non-sound components - * through the new module parameter pss_no_sound (flag). Added - * code that would allow a user to decide whether the driver should - * reset the configured hardware settings for the PSS board through - * the module parameter pss_keep_settings (flag). This flag will - * allow a user to free up resources in use by this card if needbe, - * furthermore it allows him to use this driver to just enable the - * emulations and then be unloaded as it is no longer needed. Both - * new settings are only available to this driver if compiled as a - * module.
