Subject: [Intel-gfx] [PATCH v3 10/16] misc/mei/hdcp: Fix AUTH_STREAM_REQ cmd buffer len
Date: Fri, 23 Oct 2020 17:51:06 +0530 [thread overview]
Message-ID: <20201023122112.15265-11-anshuman.gupta@intel.com> (raw)
In-Reply-To: <20201023122112.15265-1-anshuman.gupta@intel.com>
Fix the size of WIRED_REPEATER_AUTH_STREAM_REQ cmd buffer size.
It is based upon the actual number of MST streams and size
of wired_cmd_repeater_auth_stream_req_in.
Excluding the size of hdcp_cmd_header.
v2:
hdcp_cmd_header size annotation nitpick. [Tomas]
