External boost enables sequences for devices with or without GPIO1 as VSPK switch are the same if devices are put in safe mode from reset. As a previous patch put all external boost devices into safe mode from reset, all external boost devices can be handled in the same way for stream open and close. The only difference is that devices without an VSPK switch can not be put in reset and devices with it can be put into reset if a configuration is applied. The function cs35l41_hda_safe_reset is created to handle the safe reset of the chip, and as systems without VSPK switch are not supported anymore, only the CS35L41 HDA driver should check its return.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
