Subject: [PATCH 22/32] topology: decode: Fix decoding PCM formats and rates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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