X-Git-Tag: v5.4-rc1~498^2~30^2~145 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=07fbbd66b9735fe309f3bb4ad6dbfaa767e9222e;p=platform%2Fkernel%2Flinux-rpi.git drm/v3d: Drop reservation of a shared slot in the dma-buf reservations. We only set the excl (possible-writing) fence pointer and never add a shared (read-only) fence.
