From ff06c5211fc9921c45ed2fe23f43ff2e8656c402 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Thu, 21 Oct 2021 13:57:44 +0200 Subject: [PATCH 613/634] drm/vc4: kms: Don't duplicate pending commit Our HVS global state, when duplicated, will also copy the pointer to the drm_crtc_commit (and increase the reference count) for each FIFO if the pointer is not NULL. However, our atomic_setup function will overwrite that pointer without putting the reference back leading to a memory leak. Since the commit is only relevant during the atomic commit process, it doesn't make sense to duplicate the reference to the commit anyway. Let's remove it.
