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->chan.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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
