From a830df0714117574fd0d5fe98477059b3e9fd5bf Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Mon, 23 Nov 2009 22:33:27 +0100 Subject: ath9k: separate debugfs support from CONFIG_ATH_DEBUG In my setups, ath9k's debugfs files are most of the time much more useful than the messages generated by enabling CONFIG_ATH_DEBUG along with the right debug flags. Since CONFIG_ATH_DEBUG comes with a noticeable overhead on embedded systems, this patch makes it possible to use the debugfs files without that option.
