Subject: dmaengine: hsu: move memory allocation to GFP_NOWAIT
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ad53b26cd140fbea92d79a449c8ddb8d1a6f5f26;p=linux-beck.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.
