In order to avoid exposing acpi_bus_type to modules, introduce an acpi_bus_for_each_dev() helper for iterating over all ACPI device objects and make typec_link_ports() use it instead of the raw bus_for_each_dev() along with acpi_bus_type. Having done that, drop the acpi_bus_type export. No intentional functional impact. Signed-off-by: Rafael J.

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.
