Title
ASoC: mediatek: Fix error handling in mt8183_da7219_max98357_dev_probe
Summary
In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: Fix error handling in mt8183_da7219_max98357_dev_probe The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done. This function only calls of_node_put() in the regular path. And it will cause refcount leak in error paths. Fix this by calling of_node_put() in error handling too.
Severity ?
