Subject: [PATCH v3 1/8] drm/ast: Don't pin cursor source BO explicitly during update
Date: Wed,  9 Dec 2020 15:25:20 +0100	[thread overview]
Message-ID: <20201209142527.26415-2-tzimmermann@suse.de> (raw)
In-Reply-To: <20201209142527.26415-1-tzimmermann@suse.de>

Vmapping the cursor source BO contains an implicit pin operation,
so there's no need to do this manually.
