Subject: [PATCH] ASoC: fsl_esai: Remove expensive print in irq handler
Date: Tue, 21 Apr 2020 16:41:23 +0800 [thread overview]
Message-ID: <1587458483-2166-1-git-send-email-shengjiu.wang@nxp.com> (raw)
Use dev_dbg instead of dev_err in irq handler, the dev_err
is expensive, we don't need the message to be printed everytime,
which is almost a debug option.
