Current hdmi-codec driver is assuming that it will be registered from HDMI driver. Because of this assumption, each callback function has struct device pointer which is parent device (= HDMI). Then, it can use dev_get_drvdata() to get private data. OTOH, on some SoC/HDMI case, SoC has VIDEO/SOUND and HDMI IPs. This case, it needs SoC VIDEO, SoC SOUND and HDMI video, HDMI codec driver. In DesignWare HDMI IP case, SoC VIDEO (= DRM/KMS) driver tries to bind DesignWare HDMI video driver, and HDMI codec driver (= hdmi-codec). This case, above "parent device" of HDMI codec driver is DRM/KMS driver and its "device" already has private data. And, from DT and ASoC CPU/Codec/Card binding point of view, HDMI codec (= hdmi-codec) needs to have "parent device" (= DRM/KMS), otherwise, it never detect sound card. Because of these reasons, some driver can't use dev_get_drvdata() to get private data on hdmi-codec driver. This patch add new void pointer on hdmi_codec_pdata for private data, and callback function will be called with it.
