It would be useful to mention why this is done. :)

But even with this patch it seems the legacy gamma in gamma_get is not very reliable.
A failed call to gamma_set could leave wrong values in crtc->gamma_store either by calling the ioctl with lut.blue set to NULL, or call gamma_set and interrupt with a signal.
For atomic color management get_gamma won't be accurate at all if mixed with new color management.
