Subject: [PATCH v3 07/10] topology: decode: Fix decoding PCM formats and rates
Date: Tue, 14 Jul 2020 13:25:08 +0200	[thread overview]
Message-ID: <1594725911-14308-8-git-send-email-piotrx.maziarz@linux.intel.com> (raw)
In-Reply-To: <1594725911-14308-1-git-send-email-piotrx.maziarz@linux.intel.com>

Not checking _LAST format and rate, which are valid indexes in arrays,
makes data loss while converting binary to standard ALSA configuration
file.
