From de63b942acf520a25ff469cf338a99eb3da65570 Mon Sep 17 00:00:00 2001 From: Takashi Iwai <tiwai@suse.de> Date: Mon, 21 Jul 2014 16:30:54 +0200 Subject: [PATCH 11/14] pcm: route: Use get/put labels for all 3 byte formats So far, use_getput flag is set only when the src or dest format is 24bit physical width. But, also 18 and 20 bit physical width formats should set the flag, too. This patch makes the check broader to cover all 3 bytes formats.
