Subject: [PATCH] drm/bridge: cdns-mhdp8546: Remove unused functions
Date: Sun,  6 Oct 2024 00:20:17 +0100	[thread overview]
Message-ID: <20241005232017.305217-1-linux@treblig.org> (raw)

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

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.
