Subject: ASoC: Switch FSL SSI DAI over to symmetric_rates
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=08d15f034e94251606479d7ca9070994c2e2fcf0;p=openwrt%2Fstaging%2Fblogic.git

ASoC: Switch FSL SSI DAI over to symmetric_rates

The effect of symmetric_constraints should provide a standard way to
enforce the use of the same sample rate for both directions.
