Subject: [PATCH AUTOSEL for 4.9 025/156] ASoC: rsnd: fix sound route path when
 using SRC6/SRC9

From: Hiroyuki Yokoyama <hiroyuki.yokoyama.vx@...esas.com>

[ Upstream commit a1c2ff53726907aff5feb37e4cfd45c1ff626431 ]

This patch fixes the problem that the missing value of the route path
setting table and incorrect values are set in the CMD_ROUTE_SELECT
register.
