From 481b9606ec7276401c7f746fe37873855c49d1b8 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Thu, 5 Jan 2012 08:29:07 -0800 Subject: [PATCH] rtlwifi: add CONFIG_RTLWIFI_DEBUG to remove all of the debug logging code It does seem odd though to have a DBG_EMERG and not always emit it. What might also be useful for any embedded use is to add CONFIG_RTLWIFI_DEBUG to conditionally remove all of the debug logging code to reduce the largish object size. This reduces the object size by about 1/3 (250KB) when CONFIG_RTLWIFI_DEBUG is not set. $ size drivers/net/wireless/rtlwifi/built-in.o* text data bss dec hex filename 368722 55333 94224 518279 7e887 drivers/net/wireless/rtlwifi/built-in.o.new 586904 55333 127216 769453 bbdad drivers/net/wireless/rtlwifi/built-in.o.old Signed-off-by: Joe Perches Acked-by: Larry Finger Signed-off-by: John W.
