Subject: [patch] VFIO: platform: reset: fix a warning message condition
Date: Thu, 17 Dec 2015 15:27:07 +0300 [thread overview]
Message-ID: <20151217122707.GA4267@mwanda> (raw)
This loop ends with count set to -1 and not zero so the warning message
isn't printed when it should be. I've fixed this by change the postop
to a preop.
Fixes: 0990822c9866 ('VFIO: platform: reset: AMD xgbe reset module')
