4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lucas Stach <l.stach@xxxxxxxxxxxxxx>
commit 64068853bc77786d1a28abb4087d6a3e93aedbe2 upstream.
DMA buffer descriptors aren't allocated from atomic context, so they
can use the less heavyweigth GFP_NOWAIT.
