  [PATCH] iop-adma: detangle dma_alloc_writecombine() use and check "Luis R. Rodriguez" <mcgrof@do-not-panic.com> - 2015-06-16 21:50 +0200

#1166344 — [PATCH] iop-adma: detangle dma_alloc_writecombine() use and check

From: "Luis R. Rodriguez" <mcgrof@suse.com>

dma_alloc_writecombine()'s call and return value check is tangled in all
in one call. Detangle both calls as we're used to.
