Subject: [PATCH v2 25/28] ARM: mmu: Use dma_inv_range() in dma_sync_single_for_cpu()
Date: Wed, 16 May 2018 13:00:33 -0700	[thread overview]
Message-ID: <20180516200036.29829-26-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20180516200036.29829-1-andrew.smirnov@gmail.com>

The code in the if () statement is identical to already existing
dma_inv_rand(). Use it instead.
