Subject: [PATCH 2/3] platform/x86: intel_scu_ipc: Increase virtual timeout to 10s
Date: Tue, 28 Sep 2021 03:19:32 -0700	[thread overview]
Message-ID: <20210928101932.2543937-3-pmalani@chromium.org> (raw)
In-Reply-To: <20210928101932.2543937-1-pmalani@chromium.org>

Commit a7d53dbbc70a ("platform/x86: intel_scu_ipc: Increase virtual
timeout from 3 to 5 seconds") states that the recommended timeout range
is 5-10 seconds. Adjust the timeout value to the higher of those i.e 10
seconds, to account for situations where the 5 seconds is insufficient
for disconnect command success.
