From 60e915354c27035717d95af4465cfa1b42b9240a Mon Sep 17 00:00:00 2001 From: Helen Koike Date: Mon, 16 Mar 2020 22:00:43 +0100 Subject: [PATCH] media: staging: rkisp1: cap: fix return values from pm functions If no errors occurs, pm functions return usage counters, so they can return positive numbers. This happens when streaming from multiple capture devices (mainpath and selfpath). Fix simultaneous streaming from mainpath and selfpath by not failing when pm usage counters returns a positive number.
