Subject: mtd: nand: sunxi: fix call order in sunxi_nand_chip_init()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9edb47004e2afb5884d0c900cbd1ece8b2d6f403;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mtd: nand: sunxi: fix call order in sunxi_nand_chip_init()

sunxi_nand_chip_set_timings() is extracting a pointer to the nfc from the
nand->controller field, but this field is initialized after
sunxi_nand_chip_set_timings() call.
Reorder the calls to avoid any problem.
