From e06a03bdf8781d6a93a13d5bdf33d058ca498a86 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 6 Jan 2016 12:58:09 +0300 Subject: [PATCH] fsl/fman: fix the pause_time test pause_time is unsigned so it can't be less than zero. The bug means that we allow invalid pause-times. Fixes: 57ba4c9b56d8 ('fsl/fman: Add FMan MAC support') Signed-off-by: Dan Carpenter Signed-off-by: David S.
