From e43fe02fe4fde417b40f6e70b56a30190edabb2e Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Thu, 16 May 2019 16:55:43 +0200 Subject: [PATCH] drm/vc4: Check for the binner bo before handling OOM interrupt Since the OOM interrupt directly deals with the binner bo, it doesn't make sense to try and handle it without a binner buffer registered.
