From 99897efd5aa0e9671946297ede45840bc2052c07 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Fri, 15 Dec 2017 14:06:05 +0000 Subject: nvmem: core: let stride and word_size default to 1 If the caller doesn't set stride and/or word_size in struct nvmem_config then nvmem_register accepts this but we may face strange effects later due to both values being 0. Therefore use 1 as default for both values.
