[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.

It seems that the use of %ld, PTR_ERR(<foo>) isn't particularly useful now as dev_err_probe already uses %pe to emit descriptive error messages.
