Subject: drm/amdgpu: handle bo size 0 in amdgpu_bo_create_kernel_at (v2)
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=37912e963dadcc831dd2a766780ff0b8738773d8;p=linux.git

drm/amdgpu: handle bo size 0 in amdgpu_bo_create_kernel_at (v2)

Just return early to match other bo_create functions.

v2: check if the bo_ptr is NULL rather than checking the size.
