2015-08-26drm/amdgpu: adjust the judgement of removing fence callbackJunwei Zhang
The fence in the array may be skipped if wait_all is false, thus the related callback is not initialized with list head. So removing this kind callback will cause NULL pointer reference. Signed-off-by: Junwei Zhang <Jerry.Zhang@amd.com> Reviewed-by: Jammy Zhou <Jammy.Zhou@amd.com>

2015-08-25drm/amdgpu: modify amdgpu_fence_wait_any() to amdgpu_fence_wait_multiple()Junwei Zhang
Rename the function and update the related code with this modified function. Add the new parameter of bool wait_all. If wait_all is true, it will return when all fences are signaled or timeout. If wait_all is false, it will return when any fence is signaled or timeout.
