Subject: [PATCH 2/3] soundwire: intel: increase maximum number of links
From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>
Intel platforms have enabled 4 links since the beginning, newer
platforms now have 5 links. Update the definition accordingly.
This patch will have no effect on older platforms where the number of
links was hard-coded. A follow-up patch will add a dynamic check that
the ACPI-reported information is aligned with hardware capabilities on
newer platforms.
