Summary
ASoC: mediatek: mt8192-mt6359: Fix error handling in mt8192_mt6359_dev_probe
Details

In the Linux kernel, the following vulnerability has been resolved:

ASoC: mediatek: mt8192-mt6359: Fix error handling in mt8192mt6359dev_probe

The devicenode pointer is returned by ofparsephandle() with refcount incremented. We should use ofnode_put() on it when done.

This function only calls ofnodeput() in the regular path. And it will cause refcount leak in error paths. Fix this by calling ofnodeput() in error handling too.
