Subject: [PATCH] drivers/net/wireless/atmel.c: Use time_* macros
Date: Mon, 17 Mar 2008 11:36:31 +0200 [thread overview]
Message-ID: <1205746593-24820-9-git-send-email-caglar@pardus.org.tr> (raw)
In-Reply-To: <1205746593-24820-8-git-send-email-caglar@pardus.org.tr>
The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values.
So following patch implements usage of the time_after() macro, defined at linux/jiffies.h, which deals with wrapping correctly
