Subject: [PATCH v4 08/13] drm/udl: Use drm_gem_shmem_vmap_local() in damage handling
Date: Fri, 8 Jan 2021 10:43:35 +0100 [thread overview]
Message-ID: <20210108094340.15290-9-tzimmermann@suse.de> (raw)
In-Reply-To: <20210108094340.15290-1-tzimmermann@suse.de>
Damage handling in udl requires a short-term mapping of the source
BO. Use drm_gem_shmem_vmap_local().
