Subject: [PATCH 3096/4256] drm/ttm: use the same attributes when freeing
d_page->vaddr
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In function __ttm_dma_alloc_page(), d_page->addr is allocated
by dma_alloc_attrs() but freed with use dma_free_coherent() in
__ttm_dma_free_page().
Use the correct dma_free_attrs() to free d_page->vaddr.
