[PATCH 1/2] drm/panfrost: Consider dma-buf imported objects as resident

From: Adrián Larumbe
Date: Sat Nov 25 2023 - 15:55:48 EST


A GEM object constructed from a dma-buf imported sgtable should be regarded
as being memory resident, because the dma-buf API mandates backing storage
to be allocated when attachment succeeds.
