Description OSIDB Bzimport 2025-06-18 12:13:19 UTC 
In the Linux kernel, the following vulnerability has been resolved:

mmc: sdhci-of-esdhc: Fix refcount leak in esdhc_signal_voltage_switch

of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
of_node_put() checks null pointer.
