The node_id for multi-gateway ALH DAI's get overwritten with the group_id during the DAI copier's ipc_prepare op. So, save the ALH dai_index during the BE DAI hw_params in the dai_index field of struct ipc4_copier and use that to set the device ID in the configuration blob. This will avoid errors during copier init after an xrun. Note that the dai_index is typically set in topology for DMIC/SSP, but it's not used for ALH. Reclaiming this dai_index field to store the node_id does not generate a conflict with topology-defined values.

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 reStructuredText 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.
