From ccf04c51004d0b973a688a91c879e2d91780d03c Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Fri, 14 Dec 2012 11:36:41 +0100 Subject: [PATCH] mtd: omap-nand: pass device_node in platform data Pass an optional device_node pointer in the platform data, which in turn will be put into a mtd_part_parser_data. This way, code that sets up the platform devices can pass along the node from DT so that the partitions can be parsed. For non-DT boards, this change has no effect.
