    Subject[PATCH 6.0 752/862] ASoC: sunxi: sun4i-codec: set debugfs_prefix for CPU DAI component
    Date
    From: Mikhail Rudenko <mike.rudenko@gmail.com>

    [ Upstream commit 717a8ff20f32792d6a94f2883e771482c37d844b ]

    At present, succesfull probing of H3 Codec results in an error

    debugfs: Directory '1c22c00.codec' with parent 'H3 Audio Codec' already present!

    This is caused by a directory name conflict between codec
    components. Fix it by setting debugfs_prefix for the CPU DAI
    component.
