Subject: mtd: constify mtd_partition
X-Git-Tag: v4.15-rc1~25^2~12
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d4906688d49150eb77ddc9baafc3ea14bc158f03;p=thirdparty%2Fkernel%2Flinux.git

mtd: constify mtd_partition

mtd_partition are not supposed to change at runtime.
Functions 'mtd_device_parse_register' working with const mtd_partition
provided by <linux/mtd/mtd.h>. So mark the non-const structs as const.
