From 7b34734816d5170f40329598390de22d0166e4e9 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 16 Mar 2017 18:54:18 +0000 Subject: [PATCH] drm: vc4: remove redundant check of plane being non-null The pointer plane is always null on the error path at label 'fail' hence the check if it is non-null is redundant. We can therefore remove the check and the destruction of plane as well as the fail error path and instead just return an -ENOMEM ERR_PTR.
