Subject: [PATCH] ASoC: imx-hdmi: Fix refcount leak in imx_hdmi_probe
Git-commit: ed46731d8e86c8d65f5fc717671e1f1f6c3146d2
Patch-mainline: v5.19-rc1
References: git-fixes

of_find_device_by_node() takes reference, we should use put_device()
to release it. when devm_kzalloc() fails, it doesn't have a
put_device(), it will cause refcount leak.
Add missing put_device() to fix this.

Fixes: 6a5f850aa83a ("ASoC: fsl: Add imx-hdmi machine driver")
Fixes: f670b274f7f6 ("ASoC: imx-hdmi: add put_device() after of_find_device_by_node()")
