Subject: [PATCH] msi3103: Use time_before_eq()
Date: Sat, 24 May 2014 18:47:56 +0000 [thread overview]
Message-ID: <1400957276-13222-1-git-send-email-manuel.schoelling@gmx.de> (raw)
To be future-proof and for better readability the time comparisons are
modified to use time_before_eq() instead of plain, error-prone math.
Signed-off-by: Manuel Schölling <manuel.schoelling@gmx.de>
