From 7cf24421292d92556d53630e6973b34324c94103 Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Mon, 13 Sep 2010 14:46:44 +0200 Subject: [PATCH] iwlwifi: use IWL_DEBUG_SCAN for debug scanning Replace IWL_DEBUG_{INFO,HC,RC} to IWL_DEBUG_SCAN in iwl-scan.c file. Add some more IWL_DEBUG_SCAN messages. This will allow to fully debug scanning using only IWL_DL_SCAN flag. Also start one message sentence with capital letter, since that convention in iwl-scan.c file. Signed-off-by: Stanislaw Gruszka Acked-by: Wey-Yi Guy Signed-off-by: John W.
