Message-Id: <20210524165136.400702-1-jbrunet@baylibre.com>

Subject: [PATCH] ASoC: meson: use dev_err_probe
Use dev_err_probe() helper function to handle probe deferral.
It removes the open coded test for -EPROBE_DEFER but more importantly, it
sets the deferral reason in debugfs which is great for debugging.
