Subject: mtd: fsmc_nand: convert to mtd_device_register()
X-Git-Tag: v5.15~25043^2~19
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=99335d0002439b92917512dd8baeff60f774809f;p=platform%2Fkernel%2Flinux-starfive.git

mtd: fsmc_nand: convert to mtd_device_register()

Convert to mtd_device_register() and remove the CONFIG_MTD_PARTITIONS
preprocessor conditionals as partitioning is always available.
