Subject: drm/kmb: Use GEM DMA fbdev emulation
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9d8fdb04fb93bfa2edcdc15a2d48270829e9e95c;p=linux.git

drm/kmb: Use GEM DMA fbdev emulation

Use the fbdev emulation that is optimized for DMA helpers. Avoids
possible shadow buffering and makes the code simpler.
