Re: [alsa-devel] [PATCH v5 1/6] ASoC: amd:Create multiple I2S platform device Endpoint (fwd)
On line 70, adata->res is allocated with a devm function, so it shouldn't be passed to kfree later; that will lead to a double free.

Hi Julia,
This is not latest version.I have already send V6 version. The comment which you gave is for v5 old version.
sorry Vishnu, this is kbuild side problem. We will check why we didn't block the report when there's new version.
Thanks, Vishnu
