Author: Lucas Stach <[email protected]> Date: Thu Jan 26 19:08:14 2023 +0100 etnaviv: drm: fix check if BO is on a deferred destroy list list_is_linked() isn't the right function to use in order to check if the BO is on a cache bucket or the zombie list, as this checks if the next pointer of the list isn't NULL. This is always the case with the BO list item as it's always initialized, so the next pointer points to the list head itself when the BO isn't on any list. Use list_is_empty() to check if the BO is actually linked into one of the deferred destroy lists.
