From d73e4923d1b3311dda4cd1bd5d3596d75af1d1c3 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 6 May 2010 12:18:41 -0700 Subject: [PATCH] iwlwifi: split debug and debugfs options It may be desirable in some systems to have insight into the driver via debugfs, but not affect its operation via the debug logging code that is inserted everywhere when DEBUG is configured.
