From 5aaf4c27f38e2a40f5b25fd3c43cb4d57b06ae59 Mon Sep 17 00:00:00 2001 From: Chen Gang Date: Sat, 8 Jun 2013 11:57:39 +0800 Subject: [PATCH] drivers: staging: dgrp: using time_is_before_jiffies() instead of open coding 'jiffies' Need use the proper jiffy comparison macros/functions instead of open coding 'jiffies'. The original 'comparation' is always true.
