Subject: mtd: nand: Rename nand_chip .dn to .flash_node
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=61528d888adf9470db73aaadf1ff9ca35942262a;p=openwrt%2Fstaging%2Fblogic.git

mtd: nand: Rename nand_chip .dn to .flash_node

Use a more descriptive name for the device_node element in struct nand_chip .
This name matches the element name used for device_node property of a flash
in the spi-nor framework.
