CVE-2022-49683

Estado: ModificadaMedia (5.5)—

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

iio: adc: adi-axi-adc: Fix refcount leak in adi_axi_adc_attach_client

of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.
