I'd name all of these like:
intel_color_crtc_init();
intel_drrs_crtc_init();
intel_crc_crtc_init();
I think in gem side the "name functions based on first/context argument"
style has lead to serious problems wrt code organization. They still
stick to it, but I can't make heads or tails where function definitions
or declarations are supposed to be placed or found.
