From: Subash Patel <subash...@samsung.com>
This patch series is split and re-send of my original patch, after request
from Inki Dae.
Below two patches add the required error checks in drm dmabuf when the
system fails to allocate pages for the scatter-gather. This is very rare
situation, and occurs when the system is under memory pressure.
Scatter-gather asks for memory using sg_kmalloc() and this can return no
memory. Without below return value checks, the code will crash the system
due to invalid pointer access.
Subash Patel (2):
DRM: Exynos: return NULL if exynos_pages_to_sg fails
DRM: Exynos: check for null in return value of
dma_buf_map_attachment()
