From 062c5fff31be2e5324067859ef24a748f59ca029 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 25 Nov 2016 19:28:34 -0200 Subject: [PATCH] [media] media: ti-vpe: vpdma: fix a timeout loop 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.
