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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/1295ba29ac590bbb5c4a586afd408018168af10b","tags":[]},{"url":"https://git.kernel.org/stable/c/656d047dc0c29c0964d840217a0593f16aa9bc5e","tags":[]},{"url":"https://git.kernel.org/stable/c/7393372f79db940acff206b43e2905685a0c57ad","tags":[]},{"url":"https://git.kernel.org/stable/c/a3783800c9475fa58b8db0885893f96a23f949da","tags":[]},{"url":"https://git.kernel.org/stable/c/fc9937019cf7e2fe4e29f9341e6400bcd2cde721","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
