From: H Hartley Sweeten Date: Fri, 20 Aug 2010 01:18:21 +0000 (-0700) Subject: mtd: cleanup Kconfig dependencies X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=432dc821c90114f9b0e00f6752a700e937516ade;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git mtd: cleanup Kconfig dependencies Remove the MTD!=n dependency since that is handled by drivers/mtd/Kconfig. Simplify the dependency checks for mtd/chips by using if/endif blocks. Remove all default n since that is the Kconfig default.
