Description

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

staging: media: tegra-video: fix of_node_put() on VIP parse errors

tegra_vip_channel_of_parse() initializes np from dev->of_node without taking a reference, but its error paths drop one through the err_node_put label. This underflows the refcount of the VIP device's OF node when endpoint parsing fails on a malformed device tree.

The only reference the function takes on np is the success-path of_node_get() stored in vip->chan.of_node, and that one is already released by the tegra_vip_init() error path and by tegra_vip_exit().

Return errors directly instead of jumping to the bogus cleanup label.
