From 09ea9719a423fc675d40dd05407165e161ea0c48 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Fri, 9 Jul 2021 14:30:25 +0200 Subject: media: venus: venc: Fix potential null pointer dereference on pointer fmt Currently the call to find_format can potentially return a NULL to fmt and the nullpointer is later dereferenced on the assignment of pixmp->num_planes = fmt->num_planes. Fix this by adding a NULL pointer check and returning NULL for the failure case.
