Subject: [PATCH] ipw2100: RF kill switch timer power save
Date: Fri, 22 Jun 2007 21:46:50 -0700 [thread overview]
Message-ID: <20070622214650.690293f4@oldman> (raw)
Similar patch to ipw2200. Round the timer used for RF kill
switch off to 1 second boundary to save power.
Build tested only, don't have this hardware.
