[PATCH v15 09/23] drm/shmem-helper: Remove obsoleted is_iomem test
From: Dmitry Osipenko
Date: Sun Aug 27 2023 - 14:12:36 EST
Everything that uses the mapped buffer should by agnostic to is_iomem.
The only reason for the is_iomem test is that we're setting shmem->vaddr
to the returned map->vaddr. Now that the shmem->vaddr code is gone, remove
the obsoleted is_iomem test to clean up the code.
