>> drivers/dma/xgene-dma.c:1626:5: sparse: symbol 'xgene_dma_init_ring_mngr' was not declared. Should it be static?
   drivers/dma/xgene-dma.c:2088:1: sparse: symbol '__UNIQUE_ID_author__COUNTER__' has multiple initializers (originally initialized at drivers/dma/xgene-dma.c:2087)

Please review and possibly fold the followup patch.
