Subject: [PATCH] ASoC: meson: g12a-tohdmitx: override codec2codec params
Date: Mon, 29 Jul 2019 10:01:39 +0200 [thread overview]
Message-ID: <20190729080139.32068-1-jbrunet@baylibre.com> (raw)
So far, forwarding the hw_params of the input to output relied on the
.hw_params() callback of the cpu side of the codec2codec link to be called
first. This is a bit weak.
Instead, override the stream params of the codec2codec to link to set it up
correctly.
