[PATCH v2 1/4] ASoC: codecs: wcd9335: Simplify with dev_err_probe

[Krzysztof Kozlowski]

Replace dev_err() in probe() path with dev_err_probe() to:
1. Make code a bit simpler and easier to read,
2. Do not print messages on deferred probe.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>

Changes in v2:
