Subject: [PATCH 09/11] remoteproc: Update max_notifyid as we allocate vrings
Date: Wed, 19 Oct 2016 19:40:10 -0700	[thread overview]
Message-ID: <1476931212-1806-10-git-send-email-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <1476931212-1806-1-git-send-email-bjorn.andersson@linaro.org>

Vrings are now allocated as we parse the resource table, before we
boot the rproc or register any virtio devices, so it's safe to bump
max_notifyid as part of this process.
