From 03b8dcba1e6ea636a96d80f7adbf03d748d517ad Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Manuel=20Sch=C3=B6lling?= Date: Sun, 18 May 2014 12:45:48 +0200 Subject: net: 8390: use time_after() for time comparison MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit To be future-proof and for better readability the time comparisons are modified to use time_after() instead of raw math.
