Subject: dmaengine: hsu: move memory allocation to GFP_NOWAIT
X-Git-Tag: v4.14-rc1~5525^2~10
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ad53b26cd140fbea92d79a449c8ddb8d1a6f5f26;p=platform%2Fkernel%2Flinux-rpi.git

dmaengine: hsu: move memory allocation to GFP_NOWAIT

The GFP_ATOMIC is too strict, and DMAEngine documentation make an advice to use
GFP_NOWAIT. This patch does the conversion.
