Subject: nvmem: include linux/err.h from header
Patch-mainline: v4.14-rc1
Git-commit: 4da69f49e73e3c79f079de62ea940cabbbf15ae7
References: FATE#323952, FATE#322506

missing err.h header file can cause simillar errors like below
in some configurations.
"error: implicit declaration of function 'ERR_PTR'
[-Werror=implicit-function-declaration]"

This adds the missing include to ensure we can always include
the header.
