From: Joe Perches Date: Tue, 15 May 2012 21:20:32 +0000 (-0700) Subject: net: mac80211: Add and use ibss_vdbg debugging macro X-Git-Tag: v3.6-rc1~125^2~57^2~390 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=499f42bb03a9bd8a23f73e7c3886f70f52e7edc5;p=platform%2Fkernel%2Flinux-3.10.git net: mac80211: Add and use ibss_vdbg debugging macro Simplify the use of #ifdef CONFIG_MAC80211_IBSS_DEBUG/#endif by adding a logging macro to encapsulate the test. Convert the appropriate uses too. Signed-off-by: Joe Perches Signed-off-by: John W.
