Subject: mtd: ofpart: Replicate mtd cmdline "lk" option with device tree "lock" property
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ab0b00bc6ebcfbff42dedb3bf53f0ece79b27e88;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mtd: ofpart: Replicate mtd cmdline "lk" option with device tree "lock" property

The mtd partition command line parser already supports a "lk" option to mask
MTD_POWERUP_LOCK. This extends that same functionality to device tree
partition specifications.
