Subject: [PATCH 5/6] iommu/arm-smmu: Set MAX_MASTER_STREAMIDS to MAX_PHANDLE_ARGS
Date: Thu, 30 Jan 2014 19:18:08 +0100 [thread overview]
Message-ID: <1391105889-32718-6-git-send-email-andreas.herrmann@calxeda.com> (raw)
In-Reply-To: <1391105889-32718-1-git-send-email-andreas.herrmann@calxeda.com>
The DT parsing code that determines stream IDs uses
of_parse_phandle_with_args and thus MAX_MASTER_STREAMIDS
is always bound by MAX_PHANDLE_ARGS.
