From aa9746af8fa26d28d442a7415c701eb5dfeb7a2a Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 9 Jun 2010 01:46:32 -0700 Subject: [PATCH] iwlwifi: print warning about disconnected antennas When we detect that not all antennas are properly connected, we simply disable the associated chains, but never notify the user at all. Print out a warning so it is obvious that happened and we know where to start looking for related issues.
