I use and AMD polaris card with amdgpu and mesa drivers.

Previously I only had mesa-opencl-icd and ocl-icd-libopencl1 which is pulled by mesa-opencl-icd.

Trying to remove ocl-icd-libopencl1 prompts me to install nvidia-opencl packages.

It seems bug #954849 has a pretty similar bug, but found the problem while using libreoffice's opencl implementation.
