From 4fb06283edb573bee139cf358173d3801520c692 Mon Sep 17 00:00:00 2001 From: Eran Harary Date: Sun, 19 Apr 2015 10:05:18 +0300 Subject: [PATCH] iwlwifi: 8000: fallback to default NVM file Set a default NVM in case the userspace specifies a file that doesn't match the hardware version. This allows not to change the boot scripts when someone replaces the device with a newer hardware step.
