Description OSIDB Bzimport 2025-02-26 03:21:54 UTC 
In the Linux kernel, the following vulnerability has been resolved:

iio: adc: aspeed: Fix refcount leak in aspeed_adc_set_trim_data

of_find_node_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
