Subject: [PATCH 5/6] ASoC: codecs: msm8916-wcd-analog: Properly handle
 probe errors

The probe() function fails with an error for platform_get_irq_byname()
but only logs when devm_request_threaded_irq() fails. Make this
consistent and fail to probe in that case as well. In practice this
should never happen unless something is really wrong.
