Subject: [PATCH 21/26] drm: use new iterator in drm_gem_plane_helper_prepare_fb
Date: Mon, 13 Sep 2021 15:17:02 +0200 [thread overview]
Message-ID: <20210913131707.45639-22-christian.koenig@amd.com> (raw)
In-Reply-To: <20210913131707.45639-1-christian.koenig@amd.com>
Makes the handling a bit more complex, but avoids the use of
dma_resv_get_excl_unlocked().
Signed-off-by: Christian König <christian.koenig@amd.com>
