From mboxrd@z Thu Jan 1 00:00:00 1970 From: andreas.herrmann@calxeda.com (Andreas Herrmann) Date: Thu, 30 Jan 2014 19:18:08 +0100 Subject: [PATCH 5/6] iommu/arm-smmu: Set MAX_MASTER_STREAMIDS to MAX_PHANDLE_ARGS In-Reply-To: <1391105889-32718-1-git-send-email-andreas.herrmann@calxeda.com> References: <1391105889-32718-1-git-send-email-andreas.herrmann@calxeda.com> Message-ID: <1391105889-32718-6-git-send-email-andreas.herrmann@calxeda.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
