[PATCH] drm/exynos: fix pages allocation in lowlevel_buffer_allocate

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: YoungJun Cho <yj44.cho@xxxxxxxxxxx>

When drm iommu is not supported, buf->pages has to be allocated
and assigned to phys_to_page() result, which type is struct page *.
So it is sufficient to allocate buf->pages with multiple struct
page pointer size.
