Subject: [PATCH 0/2] ASoC: fsl_easrc: Fix duplicate debufs entries

Hi,

this series fixes the error regarding duplicate debugfs directory creation on
TQMa8MPxL (imx8mp) when easrc is enabled:
  debugfs: '30c90000.easrc' already exists in 'tqm-tlv320aic32'

This is caused because fsl_easrc adds two components which use the device name
as component name. Debugfs directories for each component is created, resulting
on name conflict. Fix this by adding the debugfs_prefix for both component
drivers.

Before:
$ ls /sys/kernel/debug/asoc/tqm-tlv320aic32/
30c30000.sai  30c90000.easrc  HiFi-ASRC-FE  dapm  dapm_pop_time
dma:30c30000.sai  tlv320aic32x4.1-0018

After:
$ ls /sys/kernel/debug/asoc/tqm-tlv320aic32/
30c30000.sai  HiFi-ASRC-FE  asrc:30c90000.easrc  dapm  dapm_pop_time
dma:30c30000.sai  easrc:30c90000.easrc  tlv320aic32x4.1-0018

Best regards,
Alexander
