From 2edb7a3372c76c9379d0fc00e4274ea8f018248a Mon Sep 17 00:00:00 2001 From: Moshe Harel Date: Thu, 10 Sep 2015 15:29:09 +0300 Subject: [PATCH] iwlwifi: nvm: free old section data when reading nvm file When reading external NVM file, if a section exists both in OTP and in the external file, the memory that was allocated at OTP reading is not freed. This is possible only on systems that have an external NVM file which is typically the case on embedded systems.
