As per DRM color manager design, if a userspace wants to set a correction
blob, it prepares it and sends the blob_id to kernel via set_property
call. DRM framework takes this blob_id, gets the blob, and saves it
in the CRTC state, so that, during the atomic_commit, the color correction
values from the blob can referred and applied on display controller
registers.
This patch adds this set_property support for color correction blobs
in drm framework.

You are missing the function declaration. Set it as static perhaps ?
Yes, This was meant to be used internally, I can make it static.
