From 1618b2b02a3a0ee7a6863fed4b0d22e697e7e97c Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 4 Apr 2013 10:35:23 +0200 Subject: [PATCH] iwlwifi: print warning on request_module failure If request_module() failed then we didn't have the correct opmode module that the driver needs to function, so print a warning in this case to make it more obvious what could be wrong. This still won't catch the case where the module simply doesn't exist because it wasn't compiled though.
