Subject: [PATCH RESEND 1/2] drivers: macintosh: rack-meter: limit idle ticks to total ticks
Date: Wed, 2 Mar 2016 21:59:05 +0200 [thread overview]
Message-ID: <1456948746-15640-1-git-send-email-aaro.koskinen@iki.fi> (raw)
Limit idle ticks to total ticks. This prevents the annoying rackmeter
leds fully ON / OFF blinking state that happens on fully idling
G5 Xserve systems.
