Subject: mtd: nand: fixup bounds checks for nand_{lock,unlock}()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b1a2348a1ac1380adf429035dbf3fdad0d5367bc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mtd: nand: fixup bounds checks for nand_{lock,unlock}()

Coverity noticed that these 'ret' assignments weren't being used. Let's
use them.

Note that nand_lock() and nand_unlock() are still not officially used by
any drivers.

Coverity CIDs #1227054 and #1227037
