From 6e33e30d7ae11d527ad1d65ec09a65467d6db1b2 Mon Sep 17 00:00:00 2001 From: =?utf8?q?S=2E=C3=87a=C4=9Flar=20Onur?= Date: Thu, 14 Feb 2008 17:36:49 +0200 Subject: [PATCH] drivers/net/wireless/atmel.c: Use time_* macros MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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 Cc: linux-wireless@vger.kernel.org Signed-off-by: S.Çağlar Onur Signed-off-by: John W.
