From: Jun Nie jun.nie@linaro.org Date: Tue, 10 Jan 2017 17:23:40 +0800 Subject: dmaengine: zx: fix build warning
From: Jun Nie jun.nie@linaro.org
commit 067fdeb2f391bfa071f741a2b3eb74b8ff3785cd upstream.
Fix build warning that related to PAGE_SIZE. The maximum DMA length has nothing to do with PAGE_SIZE, just use a fix number for the definition.
