From 8edf3fd6eb0649b0f19363baf23bca39c6fbdba4 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 28 May 2013 21:32:47 +0200 Subject: iwlwifi: don't print module loading error if not modular MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If the opmode modules aren't modular, there's no point in printing an error message that request_module() failed. This will happen because the probe runs during iwlwifi's init and the opmode is only added during its init.

Chain noise calibration never started because of this. Tested on intel 5300 with two antennas attached. The driver correctly disabled one chain.
