Subject: mtd: nand: gpio: return error code of nand_scan() on error
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=408bf51e92752d084d82d21e2c1f838d0ecc5eea;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mtd: nand: gpio: return error code of nand_scan() on error

The nand_scan() returns an appropriate error value when it fails.
Use it instead of the fixed error code -ENXIO.
