Re: [PATCH -next] ASoC: mediatek: mt8195: Add missing of_node_put()

Hi Bixuan,

Thanks for catching that.
I found there are other usages of of_parse_phandle() in the file.
Will you handle them together?
If not, I will prepare a patch to fix them after this patch is merged.

Thanks,
Trevor

The platform_node is returned by of_parse_phandle() should have
of_node_put() before return.
