This underflows the refcount of the VIP device's\nOF node when endpoint parsing fails on a malformed device tree.\n\nThe only reference the function takes on np is the success-path\nof_node_get() stored in vip-\u003echan.of_node, and that one is already\nreleased by the tegra_vip_init() error path and by tegra_vip_exit().\n\nReturn errors directly instead of jumping to the bogus cleanup label.",
