Subject: [PATCH 03/11] of: address: Report of_dma_get_range() errors meaningfully
Date: Thu, 26 Sep 2019 19:24:47 -0500 [thread overview]
Message-ID: <20190927002455.13169-4-robh@kernel.org> (raw)
In-Reply-To: <20190927002455.13169-1-robh@kernel.org>
From: Robin Murphy <robin.murphy@arm.com>
If we failed to translate a DMA address, at least show the offending
address rather than the uninitialised contents of the destination
argument.
