From 0e5d5442cbe3399d789d6a75c6e3a0db37f846f5 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 10 Oct 2007 11:05:44 +0100 Subject: natsemi: Use round_jiffies() for slow timers Unless we have failed to fill the RX ring the timer used by the natsemi driver is not particularly urgent and can use round_jiffies() to allow grouping with other timers.
