ASoC: SOF: sof-pci-dev: add parameter to override topology filename
[ Upstream commit 772627acfeb0e670ede534b7d5502dae9668d3ee ]
The existing 'tplg_path' module parameter can be used to load
alternate firmware files, be it for development or to handle
OEM-specific or board-specific releases. However the topology filename
is either hard-coded in machine descriptors or modified by specific
DMI-quirks.
For additional flexibility, this patch adds the 'tplg_filename' module
parameter to override topology names.
To avoid any confusion between DMI- and parameter-override, a variable
rename is added.
