[ Upstream commit24cbdb910b] The other port_hidden functions rely on the port_read/port_write functions to access the hidden control port. These functions apply the offset for port_base_addr where applicable. Update port_hidden_wait to use the port_wait_bit so that port_base_addr offsets are accounted for when waiting for the busy bit to change. Without the offset the port_hidden_wait function would timeout on devices that have a non-zero port_base_addr (e.g. MV88E6141), however devices that have a zero port_base_addr would operate correctly (e.g. MV88E6390).

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.
