[PATCH v4 09/11] drivers/dma/iop-adma: Use dma_alloc_writecombine() kernel-style
From: Luis R. Rodriguez
Date: Mon Aug 24 2015 - 15:14:26 EST
From: "Luis R. Rodriguez" <mcgrof@xxxxxxxx>
dma_alloc_writecombine()'s call and return value check is tangled in all
in one call. Untangle both calls according to kernel coding style.
