Subject: mtd: Drop FORTUNET support
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8ea9eee903f3acf5aa6bdfb831461aec063b128b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mtd: Drop FORTUNET support

The kernel has never contained the symbol SA1100_FORTUNET so the driver
never compiled and can be removed safely.
