Subject: [PATCH v3 09/16] drm/i915/hdcp: Encapsulate hdcp_port_data to dig_port
Date: Fri, 23 Oct 2020 17:51:05 +0530	[thread overview]
Message-ID: <20201023122112.15265-10-anshuman.gupta@intel.com> (raw)
In-Reply-To: <20201023122112.15265-1-anshuman.gupta@intel.com>

hdcp_port_data is specific to a port on which HDCP
encryption is getting enabled, so encapsulate it to
intel_digital_port.
This will be required to enable HDCP 2.2 stream encryption.
