Subject: [PATCH] ASoC: fsl_esai: Remove the tasklet
Date: Fri, 24 Apr 2020 14:54:06 +0800 [thread overview]
Message-ID: <1587711246-27226-1-git-send-email-shengjiu.wang@nxp.com> (raw)
Remove tasklet for it may cause the reset operation
can't be handled immediately, then there will be
endless xrun interrupt.
Fixes: 7ccafa2b3879 ("ASoC: fsl_esai: recover the channel swap after xrun")
