Subject: mtd: nand: assign mtd->name in find_full_id_nand
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=092b6a1dd0c82013f59c717b8f2ca057863183e3;p=openwrt%2Fstaging%2Fblogic.git

mtd: nand: assign mtd->name in find_full_id_nand

This patch assigned the type->name to mtd->name when mtd->name is
NULL in function "find_full_id_nand".
mtd->name is NULL may cause some problem.
