Subject: [PATCH AUTOSEL 6.1 04/27] ASoC: topology: Do not assign fields that are already set

From: Amadeusz Sławiński <amadeuszx.slawinski@...ux.intel.com>

[ Upstream commit daf0b99d4720c9f05bdb81c73b2efdb43fa9def3 ]

The routes are allocated with kzalloc(), so all fields are zeroed by
default, skip unnecessary assignments.
