Subject: drm/armada: use shmem helpers if possible
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2524fc7f634d33b044e9bf91689b932e54517980;p=linux-beck.git

drm/armada: use shmem helpers if possible

shmem_read_mapping_page() uses mapping_gfp_mask(mapping) as default gfp
mask. No reason to use shmem_read_mapping_page_gfp() directly if we want
the default behavior.
