Description OSIDB Bzimport 2025-06-18 12:02:52 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ARM: OMAP2+: Fix refcount leak in omapdss_init_of

omapdss_find_dss_of_node() calls of_find_compatible_node() to get device
node. of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() in later error path and normal path.
