From: Marc Gonzalez Date: Wed, 27 Jul 2016 09:23:52 +0000 (+0200) Subject: mtd: nand: import nand_hw_control_init() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d45bc58dd3bdcaabc1d7d8d9b0b8dee826635cc6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git mtd: nand: import nand_hw_control_init() The code to initialize a struct nand_hw_control is duplicated across several drivers. Factorize it using an inline function.
