Subject: [PATCH 07/18] thunderbolt: Use pseudo-random number as initial property block generation
Date: Thu, 4 Mar 2021 15:31:14 +0300 [thread overview]
Message-ID: <20210304123125.43630-8-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20210304123125.43630-1-mika.westerberg@linux.intel.com>
As recommended by USB4 inter-domain service spec use pseudo-random value
instead of zero as initial XDomain property block generation value.
