Unload is not working yet, it's on the TODO list.

But FWIW, here's how it currently looks in version 4
(on the SabreSD):

imx_media_csi           9663  4
imx_media_ic           12688  6
imx_media_capture      10201  2 imx_media_ic,imx_media_csi
imx_media_vdic          6909  2
imx_mipi_csi2           6293  1
ov5640_mipi            25988  1
imx_media              15532  0
imx_media_common       16093  6 
imx_media_ic,imx_media,imx_media_csi,imx_mipi_cs
i2,imx_media_capture,imx_media_vdic
