Krzysztof Kozlowski 902e15c9d4 soundwire: stream: fix programming slave ports for non-continous port maps
commit ab8d66d132bc8f1992d3eb6cab8d32dda6733c84 upstream.

Two bitmasks in 'struct sdw_slave_prop' - 'source_ports' and
'sink_ports' - define which ports to program in
sdw_program_slave_port_params().  The masks are used to get the
appropriate data port properties ('struct sdw_get_slave_dpn_prop') from
an array.

Bitmasks can be non-continuous or can start from index different than 0,
thus when looking for matching port property for given port, we must
iterate over mask bits, not from 0 up to number of ports.

This fixes allocation and programming slave ports, when a source or sink
masks start from further index.

README

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.
