Subject: [patch] [media] media: ti-vpe: vpdma: fix a timeout loop
Date: Fri, 25 Nov 2016 21:28:34 +0000 [thread overview]
Message-ID: <20161125201957.GA30161@mwanda> (raw)
The check assumes that we end on zero but actually we end on -1. Change
the post-op to a pre-op so that we do end on zero. Techinically now we
only loop 499 times instead of 500 but that's fine.
