Subject: [PATCH] iwlwifi: removing unnecessary memset in 4965 rate scale
Date: Thu, 27 Sep 2007 11:27:36 +0800	[thread overview]
Message-ID: <11908636743625-git-send-email-yi.zhu@intel.com> (raw)
In-Reply-To: <11908636732679-git-send-email-yi.zhu@intel.com>

This patch removes redundant memset in rate scale. In rs_alloc_sta,
kzalloc is used so the memset can be avoided. In rs_rate_init, it is
a bug fix since it overrides everything set in other handlers namely
add_debugfs.
