firmware: psci: Fix refcount leak in psci_dt_init
[ Upstream commit 7ff37d29fd5c27617b9767e1b8946d115cf93a1e ]
Fix a reference counter leak in psci_dt_init() where of_node_put(np) was
missing after of_find_matching_node_and_match() when np is unavailable.
Fixes: d09a0011ec0d ("drivers: psci: Allow PSCI node to be disabled")
