Subject: [Intel-gfx] [PATCH v5 11/17] misc/mei/hdcp: Fix AUTH_STREAM_REQ cmd buffer len
Date: Wed, 11 Nov 2020 11:50:45 +0530	[thread overview]
Message-ID: <20201111062051.11529-12-anshuman.gupta@intel.com> (raw)
In-Reply-To: <20201111062051.11529-1-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]
