Subject: drm/amdgpu: let bo_list handler start from 1
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=decee87a88c05980ebc545c19d4ff252052ddc3e;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

drm/amdgpu: let bo_list handler start from 1

this could prevent mis-understanding, because libdrm side will consider
no bo_list created if handleis zero
