Subject: [PATCH 5.18 0762/1095] interconnect: imx: fix max_node_id
From: Peng Fan <peng.fan@....com>
[ Upstream commit bd734481e172b4827af09c9ab06c51d2ab7201e6 ]
max_node_id not equal to the ARRAY_SIZE of node array, need increase 1,
otherwise xlate will fail for the last entry. And rename max_node_id
to num_nodes to reflect the reality.
Fixes: f0d8048525d7d ("interconnect: Add imx core driver")
