If anyone has any objections, please let me know. ------------------ From: Yuho Choi [ Upstream commit 36d46348eb5fc4bc505cd2290ddd70c25fbe6bb3 ] of_find_compatible_node() returns a referenced device node. The i.MX31 and i.MX35 early init paths use the node to map the CCM registers with of_iomap(), but never drop the node reference. Release the node after the mapping is created.
