[Intel-gfx] [PATCH 09/13] drm/i915/hdcp: HDCP2.x Refactoring to agnotic cp f/w
Suraj Kandpal

Mon Dec 5 07:05:43 UTC 2022
From: Anshuman Gupta <anshuman.gupta at intel.com>
As now we have more then one type of content protection
secrity firmware. Let change the i915_cp_fw_hdcp_interface.h
header naming convention to suit generic f/w type.
%s/MEI_/FW_
%s/mei_fw/cp_fw
%s/mei_dev/fw_dev
As interface to CP FW can be either a non i915 component or
i915 intergral component, change structure name Accordingly.
