[PATCH] drm/bridge: cdns-mhdp8546: Remove unused functions

From: linux
Date: Sat Oct 05 2024 - 19:20:44 EST


From: "Dr. David Alan Gilbert" <linux@xxxxxxxxxxx>

cdns_mhdp_hdcp_set_lc() and cdns_mhdp_hdcp_set_public_key_param()
were added by commit
6a3608eae6d3 ("drm: bridge: cdns-mhdp8546: Enable HDCP")
but never used.

Remove them.
