[alsa-devel] [PATCH v2] topology: Fix issue in parsing routes when generating topology binary

[fuweix.tang at intel.com]

From: Fuwei Tang <fuweix.tang at intel.com>

We missed parsing the index value, which is used as a use case indicator, when
processing the route objects.

This patch fixes the bug.
