Subject: [PATCH v7 02/16] ARM: LPAE: Cast the dma_addr_t argument to unsigned long in dma_to_virt
Date: Wed, 10 Aug 2011 16:03:25 +0100 [thread overview]
Message-ID: <1312988619-16804-3-git-send-email-catalin.marinas@arm.com> (raw)
In-Reply-To: <1312988619-16804-1-git-send-email-catalin.marinas@arm.com>
This is to avoid a compiler warning when invoking the __bus_to_virt()
macro. The dma_to_virt() function gets addresses within the 32-bit
range.
